We report the first documented case of malignant melanoma obstructing ureters of both moieties of a duplex kidney and contralateral single moiety ureter in a 51-year-old male. The patient presented with fever, coryzal symptoms and liver function test derangement several years after two superficial spreading melanomas were excised with clear margins. Ultrasonography demonstrated hydronephroureter in both moieties of a complete right-sided duplex kidney. Retrograde pyelograms showed bilateral hydronephroureter and filling defects in all three ureters...

OBJECTIVES: To examine temporal national trends of operative approach for cystectomy and identify demographic or clinical predictive factors that influence choice of approach. METHODS: We performed a retrospective cohort study of patients who underwent cystectomy for bladder cancer between 2010 and 2013 using the National Cancer Database (NCDB). Approach was stratified by open vs. minimally invasive (robotic or laparoscopic). Univariate Pearson chi-square and multivariate logistic regression analysis was used to assess relationships between demographic and hospital factors and the receipt of minimally invasive or open surgical approach...

OBJECTIVE: To develop a standardized digital reporting tool for cystoscopy of the urinary bladder using panoramic imaging. MATERIALS & METHODS: An image processing and stitching software (Endorama(®)) was developed to generate panoramic images from cystoscopy data. In a processing phase, algorithms were modulated and refined by reference to cystoscopy sequences (n=30). Subsequently, standard systematic cystoscopies (n=12) were recorded in patients undergoing transurethral resection of a bladder tumor in order to create panoramic images...

We describe a case of an unusual finding during robotic-assisted laparoscopic radical prostatectomy and bilateral pelvic lymphadenectomy in a 66-year-old male with Stage IIb (T2c, N0, M0) prostate adenocarcinoma. During the operation, intraperitoneal examination of the rectovesical pouch revealed calcifications and stones which were subsequently identified as gallstones. While these stones were not noted initially on this patient's preoperative multiparametric MRI (mpMRI), a retrospective review demonstrated hypointense foci in the rectovesical pouch...

OBJECTIVE: To determine the long-term impact of extravasation at initial post-urethroplasty urethrogram, we present a novel classification system and report the association of leak severity with outcome. MATERIALS AND METHODS: 91 patients underwent buccal graft urethroplasties of the bulbar urethra from 2007-2015. Median time to urethrogram was 23d. All leaks were characterized by length and width. Cutoffs for length and width were calculated using ROC curves. Each urethrogram was graded 0-3 (0=no leak) with one point given for any leak, length ≥1...

Pseudoaneurysms may cause recurrent hematuria after blunt renal trauma. We report on an 18-year old patient with radiographic manifestation of pseudoaneurysm 41 days after blunt renal trauma. Initial and follow-up imaging for recurrent hematuria including angiography was without signs of pseudoaneurysm or active bleeding. This case illustrates that recurrent gross hematuria as a typical symptom of pseudoaneurysm may be present initially in the absence of radiographic signs. Repeat angiography should be taken into consideration if recurrent bleeding persists...

We present a case of a patient who took part in a prospective sentinel lymph node (SN) study to investigate the drainage pattern from renal tumors. The patient was treated with laparoscopic radical nephrectomy (LRN), SN and non-SN lymph node dissection (LND) for a clinically node negative (cN0) left renal tumor of 6 cm (cT1b). Histopathological examination revealed a papillary type 2 pT1b renal cell carcinoma (RCC) with two para-aortic metastatic SNs (pN1). No adjuvant treatment was applied. The patient is free of disease at 63 months after surgery...

Pyogenic Granuloma is a benign vascular tumor that rarely reported in the urinary tract of pediatric population. Herein we present a case of a child followed for recurrent painless macroscopic hematuria. We performed ureteroscopy, and a whitish lesion was discovered in the upper calyx of the right kidney. The lesion resected endoscopically, and microscopic examination of the lesion was consistent with Pyogenic Granuloma. It is important for pediatricians and urologists to properly recognize Pyogenic Granuloma as a possible source of hematuria in the pediatric population...

Leiomyosarcoma is a rare and aggressive retroperitoneal tumor arising from the smooth muscle of the tunica media. The IVC accounts for > 70% of all leiomyosarcomas, with the renal vein being limited to few case reports (1)(2)(3)(4)(5). Accurate pre-operative diagnosis is rare as the origin is unclear and its involvement of the vessels makes biopsy prohibitively dangerous (6). Treatment involves radical nephrectomy followed by adjuvant radiation and/or chemotherapy, with poor prognosis (7)(8). Herein, we describe the laproscopic dissection of a retroperitoneal renal vein tumor using a robotic approach...
