Stone-free rates ranging from 77% to 100% alternative for antibiotics for sinus infection generic fucidin 10 gm fast delivery, similar to rates in the general population antibiotics give uti purchase fucidin overnight, have been reported (He et al viral infection purchase fucidin cheap online, 2007; Krambeck et al antimicrobial herbs and spices buy discount fucidin on-line, 2008b; Rifaioglu et al, 2008). Furthermore, some reports describe difficulty with percutaneous access secondary to a fibrous capsule that develops around certain transplanted kidneys and may require use of metal fascial dilators to overcome. EvaluationofOutcome Assessment and Fate of Residual Fragments In the era of open stone surgery, residual fragments of any size suggested a failed procedure. However, the definition and optimal management of residual fragments continue to generate controversy. These fragments were initially, and arbitrarily, defined as residual fragments 4 mm or less in diameter that were nonobstructive, noninfectious, associated with sterile urine, and in an otherwise asymptomatic patient (Newman et al, 1988). Since then, the term has been applied to fragments of various sizes, with most studies using a cutoff between 2 mm and 4 mm. For Duration of Ureteral Stone Presence As discussed in the natural history section on ureteral calculi, after the initially reversible physiologic changes seen with acute ureteral obstruction, chronic ureteral obstruction can ultimately lead to permanent renal damage. Patients attempting to spontaneously pass a ureteral stone should be intermittently imaged to evaluate for persistent or worsening hydronephrosis and stone location and passage. Active stone treatment of any form is indicated when obstruction has persisted for approximately 4 weeks (Singal and Denstedt, 1997). Continued renal blockage after this time may lead to irreversible kidney damage (Vaughan and Gillenwater, 1971). Expanding the definition of treatment success to also include fragments 2 mm or smaller improves the success rate to 62% to 84% (Portis et al, 2006; Macejko et al, 2009; Rippel et al, 2012). Schatloff and associates (2010) found that patients with residual fragments after semirigid ureteroscopy were significantly more likely to experience unanticipated medical visits (3% vs. In patients with infection-related calculi, the consequence of residual fragments is particularly harmful. Residual fragments may harbor offending bacteria and thus predispose to persistent infection. For patients with metabolic stone disease, complete stone removal does not prevent stone recurrence, but it does prolong the intervals between symptomatic events and treatment (Chow and Streem, 1998). The sensitivity of the method used to detect remaining fragments has important effects on the reported incidence and size of residual fragments. Plain radiography has a sensitivity of approximately 60% for detecting urinary stones (Mutgi et al, 1991; Assi et al, 2000; Ege et al, 2004; Johnston et al, 2009). Nephrotomography, although becoming obsolete in many centers, has proved superior to plain radiography in detecting residual fragments (Hjollund Madsen, 1972; Schwartz et al, 1984; Goldwasser et al, 1989). Traditionally, ultrasonography has been inferior to plain radiography in detecting urinary calculi, with particular deficiency in detecting ureteral stones (Yilmaz et al, 1998; Older and Jenkins, 2000). Hence, even under the most favorable circumstances, ultrasound may still miss up to 30% of renal stones. Despite its shortcomings, in detecting ureteral stones, ultrasound is highly effective in diagnosing hydronephrosis. The term clinically insignificant residual fragments may be a misnomer because many small residual fragments eventually become clinically significant and symptomatic by dislodging and causing obstruction, serving as niduses for further stone growth, or acting as a source for persistent infections (Streem et al, 1996; Zanetti et al, 1997; Candau et al, 2000; Delvecchio and Preminger, 2000). Moreover, complete stone removal appears to decrease the risk of stone recurrence (Singh et al, 1975; Patterson et al, 1987; Newman et al, 1988). Residual fragments are most likely to pass when located within the ureter, and least likely to pass when located in the lower pole. A similar spontaneous passage rate of 25% to 30% has been reported by others (Streem and associates, 1997; Candau et al, 2000). Fragments larger than 2 mm in greatest diameter were more likely to undergo a secondary procedure and independently predicted a postoperative stone-related event. Similarly, fragments located in the renal pelvis and ureter were associated with a stone event on multivariate analysis but also were associated with the highest likelihood of spontaneously passing (Ganpule et al, 2009; Raman et al, 2009). However, this must be balanced with the need to minimize unnecessary radiation exposure in patients.

The superficial inguinal nodes have been divided into five anatomic groups (Daseler et al infection x girl purchase fucidin 10 gm with amex, 1948): (1) central nodes around the saphenofemoral junction can antibiotics for uti cause yeast infection cheap 10gm fucidin visa, (2) superolateral nodes around the superficial circumflex vein antibiotics before tooth extraction order 10 gm fucidin, (3) inferolateral nodes around the lateral femoral cutaneous and superficial circumflex veins infection 2 cure race buy fucidin us, (4) superomedial nodes around the superficial external pudendal and superficial epigastric veins, and (5) inferomedial nodes around the greater saphenous vein. The deep inguinal nodes are fewer and lie primarily medial to the femoral vein in the femoral canal. The node of Cloquet is the most cephalad of this deep group and is situated between the femoral vein and the lacunar ligament. The external iliac lymph nodes receive drainage from the deep inguinal, obturator, and hypogastric groups. The blood supply to the skin of the inguinal region derives from branches of the common femoral artery-the superficial external pudendal, superficial circumflex iliac, and superficial epigastric arteries. Viability of the skin flaps raised during the dissection depends on anastomotic vessels in the superficial fatty layer of the Camper fascia that course lateral to medial along the natural skin lines. Because lymphatic drainage of the penis to the groin runs beneath the Camper fascia, this layer can be preserved and left attached to the overlying skin when the superior and inferior skin flaps are fashioned. On the basis of this anatomy, a transverse skin incision least compromises this blood supply. The femoral nerve lies deep to the iliacus fascia and supplies motor function to the pectineus, quadriceps femoris, and sartorius muscles. In addition, this nerve provides cutaneous sensation to the anterior thigh and should be preserved. Some of the sensory branches, however, are commonly sacrificed in the regional node dissection. The femoral triangle is bounded by the inguinal ligament superiorly, the sartorius muscle laterally, and the adductor longus medially. The floor of the triangle is composed of the pectineus muscle medially and the iliopsoas laterally. The location of the saphenofemoral junction is estimated to be at a point two fingerbreadths lateral and two fingerbreadths inferior to the pubic tubercle. Lymphatic spread occurs in a systematic fashion along the normal route of penile lymphatic drainage. The superficial lymphatic system consists of vessels draining the prepuce and skin of the penile shaft that converge dorsally and then divide at the base of the penis to drain into the right and left superficial inguinal nodes. The deep lymphatic system consists of drainage from the glans penis toward the frenulum, where large trunks are formed and encircle the corona to unite with those from the other side on the dorsum. They traverse the penis to the base within the Buck fascia, draining through presymphyseal lymphatics into the superficial inguinal nodes and the deep inguinal nodes of the femoral triangle. It is not uncommon for penile cancer to metastasize to the contralateral inguinal nodes because of crossover in the symphyseal region, and this needs to be taken into account in developing a treatment strategy. Drainage subsequently proceeds from the inguinal nodes to the ipsilateral pelvic lymph nodes. It is generally accepted that penile lymphatics drain to the inguinal nodes before proceeding into the iliac nodes (Riveros et al, 1967), although some anecdotal observations have suggested that penile lymphatics may at times drain directly to the external iliac nodes (Lopes et al, 2000). This observation is most likely related to undersampling of the inguinal nodes at the time of lymphadenectomy or at the time of pathologic review. Although penile carcinoma metastatic to the inguinal lymph nodes confers a poorer prognosis overall, aggressive lymphadenectomy is associated with improved long-term survival and potential cure (McDougal et al, 1986; Horenblas and van Tinteren, 1994). In addition, immediate resection of clinically occult lymph node metastases is associated with improved survival when compared with delayed resection of involved nodes at the time of clinical detection (Kroon et al, 2005). UrethralLymphatics Urethral lymphatic drainage runs parallel to the urethra and is located within the mucous membrane and submucosa (Spirin, 1963). The theory is that certain cancers typically do not spread to other lymph nodes without the necessary and stepwise involvement of the sentinel node first. Based on anatomic studies, the concept of orderly lymphatic progression of metastatic cells from the primary tumor to the sentinel node does seem to be likely with regard to squamous cell carcinoma of the penis. This approach has gained acceptance as this concept has become more widely accepted, and has also proven effective for both breast cancer and melanoma. The technique of sentinel node biopsy in patients with invasive squamous cell carcinoma of the penis and clinically negative inguinal regions was proposed by Cabanas (1977) after extensive study of lymphangiograms and anatomic dissections. A 5-cm incision is made parallel to the inguinal crease and centered two fingerbreadths lateral and inferior to the pubic tubercle. By insertion of the finger under the upper flap toward the pubic tubercle, the sentinel lymph node is encountered and excised. In the absence of tumor in the sentinel node, no metastases were found in the other inguinal lymph nodes in 31 patients. In addition, he reported that this node (subsequently termed the Cabanas node) was positive in 4% of patients in whom the lymph nodes were not deemed clinically suspicious. It was concluded that routine excision of this sentinel node could identify patients with micrometastatic disease earlier than waiting for clinically palpable nodes, which was standard at the time. The optimal form of management would provide the ability to identify patients with metastatic penile cancer in this cohort who are potentially curable with surgical lymphadenectomy while at the same time avoiding unnecessary surgery in patients with pathologically negative inguinal nodes. The indications for surgical assessment of inguinal lymph nodes when there is no palpable adenopathy are covered in Chapter 37. The primary goal of these procedures is to accurately determine whether inguinal nodal metastases are present while minimizing patient morbidity. A5-cm incision is made parallel to the inguinal crease and centered two fingerbreadths lateral and inferiortothepubictubercle. In large part, this is likely because this initial concept is based on a static location of the sentinel lymph node. In an attempt to improve sampling of the superficial nodal basin, Pettaway and colleagues (1995) evaluated extended sentinel node biopsy, during which all of the lymph nodes between the inguinal ligament and the superficial external pudendal vein were removed.

Rectal mucosal grafts also have been proposed for urethral reconstruction antimicrobial diet purchase genuine fucidin online, but little is known about their graft take antimicrobial laundry soap discount 10 gm fucidin with visa. In general antibiotics for sinus infection online purchase fucidin 10gm otc, the vascularity of the bowel mucosa is based on the vascularity of the underlying muscle antibiotics for sinus infection and bronchitis cheap fucidin 10 gm without prescription, with the mucosa carried on perforators. The term flap implies that the tissue is excised and transferred with the blood supply either preserved or surgically reestablished at the recipient site. Flaps can be classified on the basis of their vascularity and characterized as either random flaps. The flap is carried on the dermal or laminar plexuses; the dimensions of random flaps can vary widely from individual to individual and from body site to body site. The direct cuticular axial flap is a flap based on a vessel superficial to the superficial layer of the deep body wall fascia. If the muscle alone is carried as a flap, the overlying skin survives as a random unit. The free-flap cuticular and vascular connections are interrupted at the base of the flap. Vascular continuity is reconstituted in the recipient area by a microsurgical anastomosis. One can transfer a fascial flap based on the deep blood supply associated with the flap; the overlying skin, if it is not carried with the flap, remains as a random unit (Ponten, 1981; Tolhurst and Haeseker, 1982; Cormack and Lamberty, 1984). It has been argued that fascia is relatively avascular and cannot serve as the "blood supply" to the fasciocutaneous unit. Actually, the fascial layer acts as a trellis-the vessels are carried much like the limbs of a vine (Jordan, 1993). All tissue has extensibility, inherent tension, and the viscoelastic properties of stress relaxation and creep. These physical characteristics are important in predicting the behavior of transferred tissue. A flap is tissue that has been excised and transferred with the blood supply preserved or surgically reestablished at the recipient site. Grafts that have been successfully used for primary urethral reconstruction are the full-thickness skin graft, the bladder epithelial graft, the oral mucosal graft, and the rectal mucosal graft. The bladder epithelial graft and the oral mucosal graft have numerous vascular properties that make them desirable for urethral reconstruction. The issue of desiccation and hypertrophic growth, in the case of the bladder epithelial graft, has limited its use in the distal urethra. The results with split-thickness skin grafts are so good that full-thickness grafts are rarely used for coverage of the penis. For urethral reconstruction, skin islands based on the dartos fascia or tunica dartos have been effectively used. The dermal graft has been used for years to augment the tunica albuginea of the corpora cavernosa. Musculocutaneousperforators from the artery to a muscle vascularize the skin and overlying subcutaneous fat. They may be transferred as free flaps but are usually transferred locally, left attached to the vascular pedicle. Perforating blood vessels from rich plexuses on the superficial and deep aspects of the fascia connect to perforator vessels that communicate with the microvasculature of the overlying paddle. In genital reconstruction, these flaps are based on the dartos fascia of the penis or are free flaps from the forearm. A peninsular flap is a flap in which the vascular continuity and the cutaneous continuity of the flap base are left intact. In genitourinary reconstructive surgical procedures, we tend to use the term island flap. However, the usual case is that a skin island or paddle is elevated either on the muscle, as in the gracilis musculocutaneous flap, or on the fascia, as in local genital skin flaps. The term island flap is not synonymous with the terms skin island and skin paddle. The usefulness of these flaps and grafts is illustrated in the discussion of surgical techniques later in this chapter. There is continued interest in the use of tissue-cultured grafts or "manufactured" grafts. The likelihood of someday being able to use off-the-shelf grafts or sheets of cultured material successfully is not far in the future (Chen et al, 1999; Atala, 2002; Rotariu et al, 2002; El-Kassaby et al, 2003; Bhargava et al, 2004). Reconstructive surgery is performed with all efforts aimed at minimizing tissue injury and promoting healing. Surgical loupes are used by almost all surgeons performing adult and pediatric reconstructive genital surgery. A headlight or suction with attached light often adds to visualization, especially in deep perineal surgery. In penile cases, such as reconstruction of the fossa navicularis or correction of penile curvature, bipolar cautery is used exclusively. With cautery, the electrical charge is grounded either to a pad (monopolar) or to the opposite tong of the forceps (bipolar). In most instances, the field effects of the electricity are more confined with bipolar cautery.
