Changes in intrarenal resistive index following electromagnetic extracorporeal shock wave lithotripsy.

Introduction: Our aim was to study the changes in resistive index (RI) of the ipsilateral and contralateral kidneys following electromagnetic extracorporeal shock wave lithotripsy (SWL) of the kidney calculi.

Materials And Methods: Using color Doppler ultrasonography, the RI was determined in 21 patients with unilateral caliceal and pelvic kidney calculi. The RI of the interlobar renal arteries were measured for the regions near and far from the calculi (distance, less and more than 2 cm), before, 30 minutes after, and 1 week after SWL.

Role of postcircumcision mucosal cuff length in lifelong premature ejaculation: a pilot study.

Introduction: Premature ejaculation (PE) is the most prevalent sexual dysfunction among men. Several theories about its etiology have been made. One of the conflicting factors is the effect of circumcision on ejaculation, and there are some concerns about leaving so much mucosa during circumcision.
