Prevention of stone migration with the Accordion during endoscopic ureteral lithotripsy.

Background And Purpose: Endoscopic lithotripsy is often prolonged secondary to the retrograde migration of calculous fragments. Various balloons, baskets, and other devices have been used to prevent this migration. Our purpose is to analyze the effect of the Accordion(®) on stone migration and overall efficiency during lithotripsy.

Management of the looping vas deferens during laparoscopic orchiopexy.

Purpose: A number of variables should be assessed during laparoscopic orchiopexy, including vas anatomy. A looping vas deferens enters the inguinal canal and loops back to the abdominal cavity. This anatomical variant is not uncommonly encountered.

NAT2*5/*5 genotype (341T>C) is a potential risk factor for schistosomiasis-associated bladder cancer in Egyptians.

Arylamine N-acetyl transferase (NAT2) displays extensive genetic polymorphisms that affect the rates of acetylation of drugs and genotoxic compounds such as amine carcinogens. To investigate whether the slow acetylator genotype is a risk factor for development of bladder cancer following schistosomal infection of the urinary tract, the authors determined the frequencies of 3 common polymorphisms in the NAT2 gene (341T>C, 590G>A, and 282C>T), which are associated with impaired acetylation activity, in control subjects (n=61; mean age 34.3+/-9.

Treatment of Peyronie's disease by extracorporeal shockwave therapy: evaluation of our preliminary results.

Background: Peyronie's disease is an idiopathic disorder of the penis that produces erectile dysfunction. It affects mainly the tunica albuginea. We describe our preliminary results with extracorporal shockwave therapy (ESWT) as a new noninvasive modality for the treatment of Peyronie's disease.
