Is computed tomography-defined obstruction a predictor of urological intervention in emergency department patients presenting with renal colic?

Introduction: Our objective was to determine whether unilateral calculus-induced ureteric obstruction on computed tomography (CT) was independently associated with the need for urological intervention and 30-day return to the emergency department (ED).

Methods: We performed a retrospective cohort study of patients with symptomatic urinary calculi diagnosed by unenhanced helical CT. Stepwise regression analysis was used to determine the predictors of urological intervention and 30-day return to the ED.

Does intracytoplasmic sperm injection pose an increased risk of genitourinary congenital malformations in offspring compared to in vitro fertilization? A systematic review and meta-analysis.

Purpose: We systematically reviewed and performed a meta-analysis of the genitourinary congenital malformation rate after conception by intracytoplasmic sperm injection compared to in vitro fertilization.

Materials And Methods: We systematically reviewed studies to compare perinatal outcomes between children conceived by intracytoplasmic sperm injection vs in vitro fertilization. Studies showing genitourinary congenital malformation rates were included.

Squamous cell carcinoma of the suprapubic tract: A rare presentation in patients with chronic indwelling urinary catheters.

Squamous cell carcinoma (SCC) of the bladder is uncommon, but can arise in the setting of long-term bladder catheterization and chronic inflammation. SCC can arise primarily from the suprapubic catheter tract, but fewer than 10 such cases have been reported. We document 2 cases of SCC arising from the suprapubic tract associated with chronic indwelling urinary catheters.

Retubularization of the ileocystoplasty patch for conversion into an ileal conduit.

Introduction: We present the outcomes and long-term follow-up of patients who underwent conversion to an ileal conduit urinary diversion using the retubularized patch from the initial augmentation ileocystoplasty.

Methods: We reviewed the charts of all patients who underwent this surgery at our centre. The indications for surgery, workup, clinical outcomes and complication rates were assessed.

Assessing the accuracy of endoscopic estimates of lesion size in urology using in vitro models of the urinary tract.

Background And Purpose: Despite the frequency at which urologists endoscopically estimate lesion size, their accuracy has not been established. Our objectives were to determine the accuracy of cystoscopic and ureteroscopic estimates of lesion size using in vitro models of the urinary tract and to assess potential impacting factors.

Methods: Eleven staff urologists and 9 urology learners performed cystoscopy on a series of pig bladders containing mock papillary and flat lesions.
