A retrocaval ureter is a rare congenital cause of upper ureteric obstruction that results from entrapment of the upper ureter by the inferior vena cava (IVC) as it courses posterior to the cava. We report an interesting scenario of upper ureteric obstruction secondary to entrapment between twin segments of IVC.
A man interested in active surveillance of low-risk prostate cancer sought a second opinion after having undergone an inappropriate metastatic evaluation that demonstrated multiple enhancing liver masses. Because of his history of splenectomy for trauma, hepatic splenosis was suspected. Despite reassurance, the patient desired biopsy of the masses to confirm splenosis. The imaging features and pathophysiology...
To better delineate which factors influence the decision to undergo active surveillance of small renal masses. We identified 204 consecutive patients at our institution with clinical Stage T1 renal masses from June 2009 through June 2010. A variety of demographic and clinical characteristics were measured. Based on our previous work, the “ideal” criteria for active surveillance included tumor size...
To evaluate the success rates and complications of extracorporeal shock wave lithotripsy (ESWL) in children with renal stones in an age-dependant manner. From 2006 to 2010, 164 children (male/female ratio 1:3) with renal calculi have been treated with ESWL (PiezoLith3000 lithotripter). The children were divided into 2 age groups: group 1, 0-6 years old (n = 133); and group 2, 7-15 years (n = 31)...
Vesicouterine fistula after obstructed labor is very rare. Hysterosalpingography is the investigation of choice. Cystography primarily does not demonstrate the fistula because the intrauterine pressures are higher than the vesical pressure. A 38-year-old woman presented to us with vecisovaginal fistula and vesicouterine fistula that had developed 13 years earlier after obstructed labor and vaginal...
To evaluate the long-term outcomes of an ileal urinary reservoir in children. This was a longitudinal study of pediatric patients who had undergone total ileal substitution of the bladder. Continence status was assessed, and all patients were evaluated for kidney function and biochemical profile. Standardized growth charts were used to assess linear growth. To assess bone mineral density, dual-emission...
To demonstrate the effects of intravesical dexpanthenol use on bladder histology and lipid peroxidation in a chemical cystitis animal model. Thirty-five New Zealand rabbits were divided into 3 groups. Cystitis was conducted with transurethral intravesical hydrochloric acid instillation on the subjects in groups I and II. Then, Group I subjects were transurethrally administered intravesical dexpanthenol...
To investigate the potential protective effects of selenium and lycopene, either alone or in combination, for cisplatin-induced oxidative stress and testicular dysfunction in male rats. A total of 50 adult male Wistar rats were divided into 5 groups of 10 animals each, as follows: control group (treated with placebo); cisplatin-alone group; cisplatin + lycopene group; cisplatin + selenium group;...
To assess safety and efficacy of the periurethral constrictor for the treatment of postprostatectomy urinary incontinence. Periurethral constrictor is a minimally invasive, low-cost (€2000) device based on an adjustable occlusive mechanism. From December 2004 to March 2010 the device was implanted in 66 patients with mild to severe incontinence (3 or more pads per day) through a 3- to 5-cm perineal...
To survey a group of leading academic urologists from North America and abroad about their opinions regarding the educational value, safety, and ethics of live surgical demonstrations. An anonymous survey pertaining to live clinical demonstrations was sent to all active members of the American Association of Genitourinary Surgeons (AAGUS). Ninety (50%) members completed the survey. Most respondents...
To analyze, in a clinicopathologic correlation study, a small population of primarily white men with invasive squamous cell carcinoma of the penis for potential prognostic predictors. Penile squamous cell carcinoma is an uncommon cancer in North America. It has a wide spectrum of clinical behavior and an understudied pathogenesis. The data from 43 patients with invasive squamous cell carcinoma...
To report on assessments of face, content, and construct validity for the commercially available da Vinci Skills Simulator (dVSS). A total of 38 subjects participated in this prospective study. Participants were classified as novice (0 robotic cases performed), intermediate (1-74 robotic cases), or expert (≥75 robotic cases). Each subject completed 5 exercises. Using the metrics available in the...
To investigate the effect of hydroxyfasudil, a nonselective Rho-kinase inhibitor, on hypertension-related bladder dysfunction in spontaneously hypertensive rats (SHRs), as there is an increasing evidence that the Rho-associated protein kinase (ROCK) system plays an important role in bladder contraction. Twelve-week-old male SHRs were treated with hydroxyfasudil (1 mg/kg i.p.) once a day for 6 weeks...
