Detrusor contractility and overactive bladder in patients with cerebrovascular accident

Objectives:  A retrospective analysis of urodynamic studies was conducted to investigate detrusor contractility following cerebrovascular accident.

Renal ablation with absolute ethanol for nonfunctioning hydronephrosis.

Six adult patients underwent renal ablation with absolute ethanol for nonfunctioning hydronephrosis due to various ureteral lesions. The procedure of renal ablation consisted of 3 separate sessions: placement of percutaneous nephrostomy; transarterial embolization of the renal artery with absolute ethanol, and sclerotherapy of the renal pelvis and ureter through nephrostomy with absolute ethanol. Marked shrinkage of the treated kidney was observed in all cases without any major adverse effects throughout the observation period. Renal ablation with absolute ethanol for nonfunctioning hydronephrosis constitutes a safe and less invasive alternative to surgical nephrectomy to preserve the quality of life of the patients.

Intrarenal pelvic papillary Wilms’ tumor associated with aniridia: A case report

Background: Intrarenal pelvic Wilms’ tumor in a papillary growth is rare in children. A case of a two‐year‐old infant with Wilms’ tumor associated with congenital aniridia is reported.

Preliminary Experience with Low‐dose Desmopressin Treatment and Urinary Arginine Vasopressin Concentration as a Response Predictor for Patients with Nocturia with Nocturnal Polyuria

To assess whether urinary arginine vasopressin (AVP) concentrations adjusted for urinary creatinine (Cr) can predict responsiveness to low‐dose desmopressin for nocturia with nocturnal polyuria (NP).
