Extracorporeal shock wave lithotripsy was performed on 81 patients with urolithiasis (35 patients with ureteral stones, 25 patients with renal stones less than 2 cm in diameter, and 21 patients with renal stones more than 2 cm in diameter) at Kanbara Hospital from August to October, 1986. A 4 Fr catheter was placed transurethrally in the ureter up to the stone to identify the stone position and...

OBJECTIVES To evaluate an alternative approach to tubeless surgery that allows a second percutaneous procedure using the same nephrostomy tract. METHODS Twenty patients underwent percutaneous nephrolithotomy from September 2012 to May 2013 at our institution. Inclusion criteria were: absence of urinary infection, single puncture and operative time less than 2 h. Following the procedure the in...

BACKGROUND AND OBJECTIVE The present study retrospectively analyzed the data of 213 patients who underwent laparoscopic ureterolithotomy. METHODS We retrospectively analyzed the data of 213 patients, in whom we performed conventional laparoscopic ureterolithotomy from April 2006 and January 2015 based on the diagnosis of an upper or middle ureteral stone. Patients with large ureteral stones (...

To evaluate the safety and efficacy of retroperitoneal laparoscopic ureterolithotomy (RLU) in the treatment of proximal ureteral stones accompanied with obstructive pyelonephritis without preoperative drainage.We retrospectively reviewed 21 cases of proximal ureteral stones with infected kidney undergoing RLU between July 2013 and September 2016. Stone-induced obstructive infected hydronephrosi...

conclusions: administration of α-1a-specific blocker reduced analgesic dosage and colic episodes and rate of adverse effects after ureteroscopic lithotripsy of lower ureteral stones and decreased gravel expulsion time after ursl. results: the results showed that tamsulosin treatment group had low expulsion time (p = 0.011), low urinary tract symptoms, least analgesic needs and low adverse effec...

PURPOSE To evaluate hyoscine N-butyl bromide (HBB) and three different alpha-1 blockers in the treatment of distal ureteral stones. MATERIALS AND METHODS A total of 140 patients with stones located in the distal tract of the ureter with stone diameters of 5 to 10mm were enrolled in the present study and were randomized into 4 equal groups. Group 1 received HBB, Group 2 received alfuzosin, Gro...

Objective: To access the safety and efficacy of tubeless percutaneous nephrolithotomy (PCNL). Materials and methods: Since January 2001, 1000 consecutive tubeless PCNLs performed at our hospital were enrolled into this retrospective chart review. The average age of the patients (659 males and 341 females) was 54.4 ± 12.6 years, and 55 patients were 75 years old or older. The stone characteristi...

• Stone formation is a multifactorial process, and the incidence appears to be increasing among women. • Overall, the risk of stone formation during pregnancy does not appear to be increased. • Common presentations of stones in pregnancy include nonspecific flank or abdominal pain, fever, recurrent or persistent urinary tract infections, or microscopic hematuria. • Imaging investigations of a p...

OBJECTIVES To present to report the first case of ureteral lithiasis resolved using a new endoscopic approach, which we call microureteroscopy (m-URS) and attempts to reduce the ureteral damage caused by conventional instrumentation. MATERIAL AND METHODS We selected a 53-year-old patient with a 16-mm calculus in the right distal ureter. For endoscopic access, we used a 4.8 Fr sheath from the ...
