Radical excision of inguinal condyloma acuminatum following 51 years of untreated growth, found to be squamous cell carcinoma.

Giant condyloma acuminatum, caused by herpes simplex virus infection, is a large cauliflower shaped lesion that has a propensity to infiltrate surrounding tissues with paradoxically benign microscopic/histological appearance. This lesion is often benign, though it does have the potential for malignant transformation. Here we present a case that demonstrates this potential and describes the pathological and histological findings in detail. The report concludes with the clinical reasoning for considering surgical resection in these patients.

Association of Low Socioeconomic Status With Adverse Prostate Cancer Pathology Among African American Men Who Underwent Radical Prostatectomy.

BACKGROUND: We tested for associations between socioeconomic status (SES) and adverse prostate cancer pathology in a population of African American (AA) men treated with radical prostatectomy (RP). PATIENTS AND METHODS: We retrospectively reviewed data from 2 institutions for AA men who underwent RP between 2010 and 2015. Household incomes were estimated using census tract data, and patients were stratified into income groups relative to the study population median. Pathologic outcomes after RP were assessed, including the postsurgical Cancer of the Prostate Risk Assessment (CAPRA-S) score and a definition of adverse pathology (stage ≥ pT3, Gleason score ≥ 4+3, or positive lymph nodes), and compared between income groups. RESULTS: We analyzed data of 347 AA men. Median household income was $37,954. Low-SES men had significantly higher prostate-specific antigen values (mean 10.2 vs. 7.3; P < .01) and CAPRA-S scores (mean 3.4 vs. 2.5; P < .01), more advanced pathologic stage (T3-T4 31.8% vs. 21.5%; P = .03), and higher rates of seminal vesicle invasion (17.3% vs. 8.2%; P < .01), positive surgical margins (35.3% vs. 22.1%; P < .01), and adverse pathology (41.4% vs. 30.1%; P = .03). Linear and logistic regression showed significant inverse associations of SES with CAPRA-S score (P < .01) and adverse pathology (P = .03). CONCLUSION: In a population of AA men who underwent RP, we observed an independent association of low SES with advanced stage or aggressive prostate cancer. By including only patients in a single racial demographic group, we eliminated the potential confounding effect of race on the association between SES and prostate cancer risk. These findings suggest that impoverished populations might benefit from more intensive screening and early, aggressive treatment of prostatic malignancies.

Spontaneous passage of ureteral stones in patients with indwelling ureteral stents.

INTRODUCTION: To determine rates of spontaneous ureteral stone passage in patients with indwelling ureteral stents, and to identify factors associated with the spontaneous passage of stones while a ureteral stent is in place. MATERIALS AND METHODS: From our institutional database, we identified patients who underwent ureteroscopic procedures for stone disease between January 1, 2013 and March 1, 2015. We compared the rates of spontaneous stone passage between patients who had previously undergone ureteral stent placement and those who had not. In patients with indwelling stents, multivariate logistic regression was performed to identify factors associated with spontaneous stone passage. RESULTS: A total of 194 patients met inclusion criteria. Spontaneous stone passage rates were similar in the stented (17/119, 14%) and non-stented (15/75, 20%) groups (p = 0.30). In bivariate analysis of stented patients, smaller stone size (p < 0.001) and distal stone location (p = 0.01) were significantly associated with spontaneous stone passage. Multivariate logistic regression analysis of stented patients showed that only small stone size was significantly associated with the likelihood of stone passage (p = 0.01), whereas stent duration, stone location, and stone laterality were not. CONCLUSIONS: A small, but clinically significant percentage of ureteral stones pass spontaneously with a ureteral stent in place. Small stone size is associated with an increased likelihood of spontaneous passage in patients with indwelling stents. These findings may help to identify patients who can potentially avoid additional surgical procedures for definitive stone removal after ureteral stent placement.

Use of Age and Medical Comorbidity to Assess Long-term Other-cause Mortality Risk in a Cohort of Men Undergoing Prostate Biopsy at an Academic Medical Center.

OBJECTIVE: To assess life expectancy and biopsy outcomes in men undergoing prostate biopsy at an academic medical center. METHODS: We analyzed men who underwent prostate biopsy at our medical center between July 2012 and June 2014. Long-term other-cause mortality risk was determined using survival tables. Indications for biopsy and biopsy outcomes were assessed, and compared among men with varying mortality risks. RESULTS: A total of 417 men underwent prostate biopsy, in whom 14-year other-cause mortality risk ranged from 9% to 74%. One hundred ninety-three men (46.3%) were considered low-mortality risk (<40% risk of 14-year mortality), 131 (31.4%) intermediate risk (41%-55% 14-year mortality), and 93 (22.3%) high risk (>55% 14-year mortality). Of the 417 patients who underwent biopsy, 149 (35.7%) were found to have prostate cancer. There was no significant difference in the rate of positive biopsies (P = .72), distribution of Gleason scores (P = .60), or percentage of positive biopsy cores (P = .74) between mortality risk groups. However, by UCSF Cancer of the Prostate Risk Assessment score, there was significant trend toward higher-risk prostate cancer in men with intermediate and high-mortality risk (P = .04). CONCLUSION: In this analysis, a large number of men with limited life expectancies underwent prostate biopsy. The majority of these men had negative biopsies or low-risk cancers, suggesting that they were unlikely to benefit from biopsy. To avoid potentially unnecessary prostate biopsies, the practitioner must give serious consideration to a patient's age and medical comorbidities before making a recommendation as to whether biopsy should be performed.

Evidence of prostate cancer "reverse stage migration" toward more advanced disease at diagnosis: Data from the Pennsylvania Cancer Registry.

PURPOSE: The widespread adoption of prostate-specific antigen-based prostate cancer screening caused a stage migration toward earlier stage disease at diagnosis. We investigated whether this stage migration has persisted in a contemporary analysis of a population-based statewide cancer registry. MATERIALS AND METHODS: We analyzed the Pennsylvania Cancer Registry, a statewide registry of all newly diagnosed cancers. Data were collected on prostate cancers diagnosed between 1992 and 2012. We determined age-adjusted prostate cancer incidence and mortality rates, as well as the distribution of tumor stage (localized, regional, or metastatic) at diagnosis, and assessed for changes in these variables over time using joinpoint analysis. RESULTS: Between 1992 and 2012, 210,831 new cases of prostate cancer were diagnosed in Pennsylvania, and 33,948 men died of disease. Age-adjusted prostate cancer incidence rates, and specifically the incidence of localized disease, have decreased dramatically since 2007 to 2008. Due to the decreased diagnosis of localized disease, regional and metastatic tumors have made up a greater percentage of all prostate cancer diagnoses in recent years, despite a relatively stable incidence of these advanced stage tumors. CONCLUSIONS: Over the past 2 decades, age-adjusted prostate cancer incidence rates in Pennsylvania have decreased, primarily because of the decreased detection of early-stage disease. There has been a corresponding shift toward more advanced disease at diagnosis. These findings may be explained by the decreased use of prostate-specific antigen-based screening, among other factors. The 2012 United States Preventative Services Task Force recommendations against prostate cancer screening may exacerbate this concerning trend, potentially resulting in an increase in prostate cancer-specific mortality.

Multifocal Renal Fungal Abscesses.

We report a case of multiple fungal renal abscesses in a 36-year-old woman with a history of diabetes and intravenous substance use disorder. The patient presented with fever and hematuria, and was found to be bacteremic and fungemic. She was initially managed with broad-spectrum antibiotics and antifungals. She remained febrile and imaging on treatment day 14 showed no improvement of the renal abscesses. Thus, a nephrectomy was performed, after which the patient defervesced and follow-up blood cultures were negative. There is a paucity of literature regarding management of multifocal fungal renal abscesses that fail to respond to medical management.

Trends in Urology Residents' Exposure to Operative Urotrauma: A Survey of Residency Program Directors.

OBJECTIVE: To determine longitudinal trends in resident exposure to urotrauma and to assess whether presence of Genitourinary Reconstructive Surgeon (GURS) faculty has impacted exposure and career choice. METHODS: An identical, 31-question multiple-choice survey was sent to program directors of Accreditation Council for Graduate Medical Education (ACGME)-accredited urology residency programs in 2006 and 2013. The areas of focus included program demographics, extent of urotrauma exposure, program director perceptions regarding educational value of urotrauma, and impact of GURS fellowship trained faculty. Responses were de-identified, compiled, and compared for differences. RESULTS: Response rates were 57% (64/112) and 43% (53/123) for the 2006 and 2013 survey, respectively (P = .03). Trauma Level 1 designation (56/64 [89%] vs 44/53 [88%], P = .84) and presence of GURS faculty (22/64 [34%] vs 22/53 [43%], P = .43) were similar between survey periods. Although survey respondents felt urotrauma volume had remained constant (34/64 [53%] vs 30/53 [56%], P = .71), more recent respondents reported that conservative management strategies negatively impacted resident exposure (14/64 [22%] vs 23/53 [43%], P = .01). Residencies with GURS faculty in 2013 (22/53, 42%) were positively associated with residents publishing urotrauma literature (9/22 [41%] vs 4/31 [13%], P = .02), the presence of multidisciplinary trauma and urology conferences (3/22 [14%] vs 0/31 [0%], P = .03), and residents matriculating to GURS fellowships (15/22 [68%] vs 10/31 [32%], P = .009). CONCLUSION: Many contemporary urology residencies report poor resident exposure to urotrauma during training. Although presence of GURS faculty may influence resident career choice, additional strategies may be warranted to expose residents to urotrauma during training.

Stone formation from nonabsorbable clip migration into the collecting system after robot-assisted partial nephrectomy.

We describe a case in which a Weck Hem-o-lok clip (Teleflex, Research Triangle Park, USA) migrated into the collecting system and acted as a nidus for stone formation in a patient after robot-assisted partial nephrectomy. The patient presented 2 years postoperatively with left-sided renal colic. Abdominal computed tomography scan showed a 10 millimeter renal calculus in the left middle pole. After using laser lithotripsy to fragment the overlying renal stone, a Weck Hem-o-lok clip was found to be embedded in the collecting system. A laser fiber through a flexible ureteroscope was used to successfully dislodge the clip from the renal parenchyma, and a stone basket was used to extract the clip.

Testicular seminomatous mixed germ cell tumor with choriocarcinoma and teratoma with secondary somatic malignancy: a case report.

INTRODUCTION: Testicular tumors are a heterogeneous group of neoplasms exhibiting diverse histopathology and can be classified as seminomatous and non-seminomatous germ cell tumor types. Mixed germ cell tumors contain more than one germ cell component and various combinations have been reported. Here, we present a rare case of a mixed germ cell tumor composed of seminoma, choriocarcinoma and teratoma with a secondary somatic malignancy. CASE PRESENTATION: A 31-year-old Caucasian man presented with splenic rupture to our hospital. A right-sided testicular swelling had been present for 6 months and his alpha-fetoprotein, beta-human chorionic gonadotropin, and lactose dehydrogenase were increased. An ultrasound of his scrotum revealed an enlarged right testis with heterogeneous echogenicity. Multiple hypervascular lesions were noted in his liver and spleen. He underwent transcatheter embolization therapy of his splenic artery followed by splenectomy and right-sided orchiectomy. A computed tomography scan also showed metastasis to both lungs. During his last follow up after four cycles of cisplatin-based chemotherapy, the level of tumor markers had decreased, decreases in the size of his liver and pulmonary lesions were noted but new sclerotic lesions were evident in his thoracolumbar region raising concern for bony metastasis. CONCLUSIONS: Prognosis of testicular tumor depends mainly on the clinical stage, but emergence of a sarcomatous component presents a challenge in the treatment of germ cell tumors and the histological subtype of this component can be used as a guide to specific chemotherapy in these patients.

Single-surgeon experience with robot-assisted ureteroneocystostomy for distal ureteral pathologies in adults.

PURPOSE: To demonstrate our technical approach for robot-assisted ureteroneocystostomy (R-UNC) for benign and malignant distal ureteral pathologies. MATERIALS AND METHODS: Between January 2009 and January 2013, a total of 10 patients underwent R-UNC in the distal ureter by a single surgeon. Indications for R-UNC were as follows: idiopathic (3), fistula (2), iatrogenic (2), malignancy (2), and chronic vesicoureteral reflux (1). RESULTS: Tension-free anastomosis was attained in all 10 R-UNC procedures. A psoas hitch was performed in 6/10 cases (60%). Intravesical and extravesical reimplantations were completed in 5/10 (50%) and 5/10 cases (50%), respectively. A nonrefluxing ureter was constructed in 2/10 cases (20%). The patients' mean age was 52.9±16.6 years, their mean body mass index was 30.8±6.3 kg/m(2), the mean operative time was 211.7±69.3 minutes, mean estimated blood loss was 102.5±110.8 mL, and mean length of stay was 2.8±2.3 days. There were no intraoperative complications. There was one Clavien-Dindo grade I and one Clavien-Dindo grade II postoperative complication. The mean postoperative follow-up duration was 28.5±15.5 months. Two patients had recurrence of ureteral strictures at 3 months postoperatively and were managed successfully with balloon dilation. CONCLUSIONS: Our technique for R-UNC demonstrates good perioperative outcomes. However, underlying periureteral inflammation and pelvic adhesions may predispose patients for stricture recurrence after R-UNC.

Novel use of indocyanine green for intraoperative, real-time localization of ureteral stenosis during robot-assisted ureteroureterostomy.

OBJECTIVE: To present a novel method to intraoperatively localize ureteral strictures during robot-assisted ureteroureterostomy via indocyanine green (ICG) visualization under near-infrared (NIR) light. MATERIALS AND METHODS: Seven patients underwent robot-assisted ureteroureterostomy for ureteral stricture by a single surgeon (D.D.E.). Intraoperative localization of ureteral stricture involved instilling ICG (25 mg in 10 mL distilled water) above and below the level of stenosis through a ureteral catheter or a percutaneous nephrostomy tube, or both. The fluorescent tracer was detected as a green color using the NIR modality on the da Vinci Si (Intuitive Surgical, Sunnyvale, CA). All patients consented to off-label use of ICG after full disclosure. RESULTS: Intraoperative ICG injection and visualization under NIR light assisted in the performance of a tension-free anastomosis in all patients. At the time of surgery, mean age was 55.7 ± 12.4 years and mean body mass index was 30.3 ± 5.8 kg/m(2). Mean operative time was 171.3 ± 52.4 minutes, mean estimated blood loss was 175.0 ± 146.5 mL, and mean length of ureteral excision on pathologic analysis was 1.6 ± 0.7 cm. There were no immediate or delayed adverse effects attributable to intraureteral ICG administration. Mean hospital length of stay was 1.6 ± 1.5 days, with no postoperative complications. Mean follow-up was 5.9 ± 1.5 months, and all cases were clinically and radiographically successful at last follow-up. CONCLUSION: Intraureteral injection of ICG with visualization under NIR light allows for real-time delineation of the ureter. Additionally, ICG administration aids in discerning healthy ureter from diseased tissue, further assisting successful robotic ureteral repair.

Single surgeon experience with robot-assisted ureteroureterostomy for pathologies at the proximal, middle, and distal ureter in adults.

PURPOSE: To describe our initial experience with robot-assisted ureteroureterostomy (RUU) at the proximal, middle, and distal ureter. MATERIALS AND METHODS: Twelve consecutive patients underwent RUU by a single surgeon (D.D.E.) between July 2009 and November 2012. Indications included three iatrogenic injuries, two impacted stones, two ureterovaginal fistulas, two idiopathic ureteral strictures refractory to conservative treatment, one primary transitional cell carcinoma of the ureter, one colon cancer metastasis to the ureter, and one invasive endometriosis. There were two proximal, three middle, and seven distal ureteral pathologies. RESULTS: Tension-free anastomosis was achieved in all 12 patients. All patients with proximal and middle ureteral pathology received concomitant downward nephropexy (DN) as a standard part of RUU. Mean age of patients at the time of surgery was 52 years (range 30-69), mean body mass index was 30.0 kg/m(2) (range 21-38), mean operative room time was 190 minutes (range 104-354), mean estimated blood loss was 181 mL (range 50-400), and mean length of excised ureter on pathologic analysis was 2.0 cm (range 1.0-4.5). There was one intraoperative complication in which liver and gallbladder laceration occurred during trocar placement. Mean length of hospital stay was 1.4 days (range 1-5), and there were no postoperative complications. Mean follow up was 10 months (range 3-36). One patient had a ureteral stricture recurrence at 7 months postoperatively that led to renal unit loss and eventual nephrectomy. CONCLUSION: RUU is feasible, safe, and demonstrates good outcomes for pathologies at the proximal, middle, and distal ureter. Concomitant DN during RUU may assist in achieving a tension-free anastomosis for proximal and middle ureteral repairs.

Detecting DNA methylation of the BCL2, CDKN2A and NID2 genes in urine using a nested methylation specific polymerase chain reaction assay to predict bladder cancer.

PURPOSE: Detection of methylated DNA has been shown to be a good biomarker for bladder cancer. Bladder cancer has the highest recurrence rate of any cancer and, as such, patients are regularly monitored using invasive diagnostic techniques. As urine is easily attainable, bladder cancer is an optimal cancer to detect using DNA methylation. DNA methylation is highly specific in cancer detection. However, it is difficult to detect because of the limited amount of DNA present in the urine of patients with bladder cancer. Therefore, an improved, sensitive and noninvasive diagnostic test is needed. MATERIALS AND METHODS: We developed a highly specific and sensitive nested methylation specific polymerase chain reaction assay to detect the presence of bladder cancer in small volumes of patient urine. The genes assayed for DNA methylation are BCL2, CDKN2A and NID2. The regions surrounding the DNA methylation sites were amplified in a methylation independent first round polymerase chain reaction and the amplification product from the first polymerase chain reaction was used in a real-time methylation specific polymerase chain reaction. Urine samples were collected from patients receiving treatment at Wolfson Medical Center in Holon, Israel. RESULTS: In a pilot clinical study using patient urine samples we were able to differentiate bladder cancer from other urogenital malignancies and nonmalignant conditions with a sensitivity of 80.9% and a specificity of 86.4%. CONCLUSIONS: We developed a novel methylation specific polymerase chain reaction assay for the detection and monitoring of bladder cancer using DNA extracted from patient urine. The assay may also be combined with other diagnostic tests to improve accuracy.

Gunshot wounds to the scrotum: a large single-institutional 20-year experience.

UNLABELLED: Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Penetrating trauma to the scrotum often requires operative intervention, with testicular salvage only possible when enough testicular tissue can be re-approximated in the traumatic setting. The present report represents the largest series of gunshot wound trauma to the scrotum in the literature. Further, it validates recommendations of the European Association of Urology guidelines on urological trauma that advocate operative intervention due to minimal rates of patient morbidity and the inherent limitations of scrotal ultrasonography in discerning testicular compromise. OBJECTIVE: To report our 20-year experience of gunshot wounds (GSWs) to the scrotum and outline the management of this traumatic injury. PATIENTS AND METHODS: We queried our institutional database for patients presenting with GSWs to the scrotum between 1985 and 2006. All patients underwent the standard trauma evaluation upon presentation, including physical examination of the external genitalia. Management was dictated by the presence or absence of a penetrating injury to the scrotum and associated traumatic injuries. Nonoperative and operative management of traumatic injury to the scrotum were used. Testicular salvage was performed when anatomically feasible. If testicular salvage was not feasible, an orchiectomy was performed. RESULTS: Scrotal exploration was performed in 91 (94%) patients while six (6%) patients were treated nonoperatively. Testicular injury was found in 44 (48%) patients undergoing exploration, six (7%) of whom had bilateral testicular injuries, which gave a total of 50 injured testicles. Of the injured testicles, 24 (48%) could not be salvaged and required orchiectomy, while 26 (52%) were debrided and repaired. The most common associated genitourinary (GU) injuries were to the corpora cavernosum (n= 20 [21%]) and urethra (n= 10 [10%]). Soft tissue injury of the extremities occurred in 54 patients (56%), representing the most common non-GU-associated injury. Postoperative complications occurred infrequently: one patient (1%) returned for abscess drainage and one (1%) for haematoma evacuation. CONCLUSIONS: The present report confirms that any patient with a penetrating injury to the scrotum should undergo immediate scrotal exploration. A low clinical suspicion for performing additional studies to rule out associated urethral and/or penile injury is clinically warranted. Testicular loss occurs in ≈50% of injured testicles.

Penile intraepithelial neoplasia and other premalignant lesions of the penis.

Invasive penile cancer is an aggressive malignancy that often requires partial or complete penile amputation. Premalignant penile lesions, such as penile intraepithelial neoplasia, will have been present prior to the development of invasive disease in a substantial percentage of patients. Early detection and treatment of premalignant penile lesions may prevent malignant progression while avoiding penile amputation. This review focuses on premalignant penile lesions and the associations of these lesions with the development of invasive penile cancer.

Evaluation and management of gunshot wounds of the penis: 20-year experience at an urban trauma center.

BACKGROUND: Although gunshot injuries to the penis occur relatively infrequently in patients with penetrating trauma, they often present dilemmas of subsequent evaluation and management. We review our extensive experience with gunshot wounds to the penis at a high volume urban trauma center. METHODS: The urologic trauma database was retrospectively reviewed to extract and compile information from the records of 63 patients treated for gunshot wounds to the penis. Data were accumulated for a 20-year period from 1985 to 2004 with regard to findings on physical examination, diagnostic evaluation, associated injuries, management, and outcome. We detail our technique of penile exploration and artificial erection in the management of these injuries. RESULTS: Penile gunshot wounds were associated with additional injuries in 53 of 63 (84%) patients. A total of 48 (76%) patients were taken to the operating room and 44 (70%) penile explorations were performed. Evaluation included retrograde urethrogram in 50 of 63 (79%) patients and was diagnostic for urethral injury in 11 of 12 (92%) cases. Primary urethral repair was performed in 8 of 12 (67%) patients with urethral injury versus 4 of 12 (33%) who underwent urinary diversion by means of suprapubic cystotomy. CONCLUSIONS: Evaluation and management of gunshot wounds to the penis may potentially be complex. Retrograde urethrogram should be performed in all cases except the most insignificant and superficial wounds. We describe our technique of penile exploration and artificial erection, noting excellent results in patients for whom follow-up is available. Additional studies are needed to prospectively evaluate techniques for management of gunshot urethral injuries.

HIV-AIDS: urologic considerations.

The prevalence of HIV continues to grow in the United States and worldwide. HIV-positive patients experience many genitourinary disease processes. With improvements in HIV therapy, patients have questions and concerns pertaining to their quality of life. This article reviews conditions such as HIV-related urinary tract infections, urolithiasis, voiding dysfunction, fertility, sexual dysfunction, HIV-related nephropathy, malignancies, and occupational exposure and prophylaxis. Knowledge of the various HIV manifestations of genitourinary conditions and their treatment options benefits clinicians and improves patient outcomes.
