Abstract Introduction: Contrast-enhanced cross-sectional imaging is essential to the urologist's practice. Traditionally, patients with impaired renal function could not be imaged with a computed tomography (CT) scan with contrast due to the risk of contrast-induced nephropathy (CIN). These patients could alternatively be imaged by magnetic resonance imaging (MRI) with gadolinium. However, the recent identification of the association between nephrogenic systemic fibrosis (NSF) and gadolinium administration has created significant challenges for urologists and radiologists when faced with the need for evaluation with contrast-enhanced cross-sectional imaging. In this review, we summarize the most comprehensive articles discussing both NSF and… More >

Abstract Introduction: To estimate the prevalence of chronic prostatitis (CP)-like symptoms in African adolescents, examining the impact of demographic factors, CP-like symptoms (i.e., pain, urinary) and depressive symptoms on quality of life (QoL).
Materials and methods: Community dwelling African males aged 16-19 years (M = 16.97; SD = .88; n = 166), attending secondary school participated. CP-like case identification was based on NIH-Chronic Prostatitis Symptom Index definition (NIH-CPSI; pain in perineum and/or with ejaculation and NIH-CPSI total pain score of ≥ 4 [mild] and ≥ 8 [moderate-severe]). The Patient Health Questionnaire (PHQ) assessed depressive symptoms. CP-like point prevalence… More >

Abstract Introduction: Little is known regarding factors that contribute to the long term success or failure of the transobturator male sling for stress urinary incontinence. The objective of this study was to compare the outcomes of the transobturator male sling for stress urinary incontinence based on body mass index (BMI).
Materials and methods: A retrospective review was performed of 31 transobturator male slings placed at a single institution from 2008 to 2010. Success of the procedure was defined as resolution of leakage or great improvement of leakage by the Patient Global Impression of Improvement scale and lack of… More >

Abstract Introduction: To assess the technical feasibility and safety of trajectory image-guided percutaneous renal cryoablation in a porcine model.
Materials and methods: Six pigs (12 kidneys) were utilized. Only the posterior and lateral regions of the kidneys were considered. A bone-anchored dynamic reference frame (DRF) was inserted into the iliac crest and the O-Arm and StealthStation TREON System (OASSTS, Medtronic, CO, USA) was used to acquire 3-dimensional (3D) imaging of the kidneys. A hand-held pointing device was crafted from a cryoablation needle (Galil Medical, MN, USA) and an optical reference frame. The hand-held pointer/cryoablation needle ("cryoprobe") was then… More >

Abstract Introduction: Depression and benign prostatic hyperplasia (BPH) are prevalent, especially in older patient populations. Emerging data suggest potential interactions between depression and BPH. We sought to assess whether the questions of the International Prostate Symptom Score (IPSS), specifically the quality of life (QoL) question, predict depression.
Materials and methods: We asked 541 consecutive male patients over the age of 40 in a tertiary care clinic to self-administer the IPSS QoL score and the Geriatric Depression Scale (GDS), a validated screening tool for depression. Receiver operating characteristics (ROC) curves were depicted and used to determine the area under… More >

Abstract Introduction: This study aims to assess the influence of different prognostic factors on the survival of upper tract urothelial carcinoma (UTUC) managed by nephroureterectomy and to investigate whether these factors have independent prognostic significance.
Materials and methods: A retrospective review of institutional databases from two teaching hospitals identified 269 consecutive patients with UTUC managed with nephroureterectomy between 1985 and 2005. The mean follow-up was 80.6 months (median 70.3 months), completed until January 2009. Tumor location and other clinicopathological variables were analyzed in relation to survival. Data collected included age, gender, tumor characteristics (pT stage, grade, lymph node… More >

Abstract Introduction: Treatment of the elderly patient with a small renal mass is becoming a common conundrum, with scant data available to support treatment decisions. The goal was to assess the risk of surgical treatment for renal cell carcinoma (RCC) in the elderly compared to their younger counterparts.
Materials and methods: A prospectively maintained database of all renal tumors between August 2004 and November 2009 was used. Patients who underwent extirpative treatment for RCC were divided into two groups based on age: < 75 years and ≥ 75 years. Primary outcome measures included the likelihood of undergoing partial… More >

Abstract A “corkscrew deformity” of the proximal ureter is a rare congenital anomaly that typically lacks any postnatal clinical significance. The rarity of this entity, however, has not allowed the clarification of its natural history and the ideal approach to its management.
We herein present a case of a 27-year-old female patient who presented with right flank pain and significant hydronephrosis. On retrograde ureterography, a typical spiral configuration of the proximal ureter was noted. The patient underwent successful reconstruction by laparoscopic transperitoneal dismembered pyeloplasty. We report the first use of laparoscopic reconstruction for the management of More >

Abstract Recurrent renal cell carcinoma (RCC) that presents as a solitary metastasis to the bladder is extremely rare. We report our experience with two patients who presented with hematuria within 1 year of their radical nephrectomy. Both patients underwent endoscopic resection of the tumor metastasis. One patient developed a metastasis in the head of pancreas 12 months following endoscopic resection. The other patient developed bilateral femoral and spinal bone metastasis. Our aim is to report our experience, and discuss the proposed modes of spread, management and prognosis. More >

Abstract We report a case of a 72-year-old male that underwent two sets of transrectal prostatic needle biopsy (TPNB) within 9 month period. Pathology showed unremarkable benign prostatic tissues in the first group of biopsies while extensive diffuse inflammation with the characteristic features of malakoplakia in the second set. Three cores in the repeat biopsy contained foci of prostatic adenocarcinoma as well. Occurrence of malakoplakia several months after TPNB in our case suggests that microorganisms may have been inoculated to the prostate during the biopsy procedure. We believe that malakoplakia must be added to the list More >

Abstract Testicular ischemia is typically seen with cases of testicular torsion. Twisting of the spermatic cord and compromise of testicular blood supply can induce testicular loss if not promptly discovered and treated. Non-torsion causes of testicular ischemia are uncommon with rare citations in the literature. Herein, we present a case of testicular ischemia induced by traumatic thrombosis of the spermatic vessels. More >

Abstract Holmium laser resection of the prostate (HoLRP) was first described by Gilling et al in 1995. HoLRP has now evolved into holmium laser enucleation of the prostate (HoLEP) with the advent of the intravesical soft-tissue morcellator. The procedure involves anatomical dissection of the prostatic tissue off the surgical capsule in a retrograde fashion using a high-powered holmium laser followed by intravesical morcellation of the prostatic tissue. Some groups believe that the HoLEP procedure is the endoscopic equivalent to a simple open prostatectomy and may be superior to transurethral resection of the prostate (TURP) or even More >

Abstract Introduction: Placement of anterior abdominal wall trocars during laparoscopic radical prostatectomy (LRP) carries the risk of inadvertent injury to the inferior epigastric artery (IEA) and potential conflict between midline and lateral ports. We described and evaluated a new measured port placement approach.
Materials and methods: The intervention group included patients who underwent LRP using a specifically measured five-port approach. The medial 10 mm ports were placed 5 cm from the patient’s midline at a level midway between the anterior superior iliac spine (ASIS) and the umbilicus. The control group had five ports placed at the surgeon’s discretion.… More >

Abstract Introduction: The objective of our study was to determine whether the dorsal venous complex (DVC) control technique influences positive apical margins following robotic-assisted laparoscopic radical prostatectomy (RALRP).
Materials and methods: A total of 1058 patients who underwent RALRP at City of Hope between June 2007 and October 2009 were included in the analysis. Endoscopic stapling and suture ligation of the DVC were compared. Positive apical margins were identified and compared based on the DVC control technique. Recurrence probability was estimated using the Kaplan-Meier method, and logistic regression analysis was used to predict the odds of positive apical margins.
