INTRODUCTION The AUA/EAU Ureteral Stones Guideline Panel reported that the stone free rate for the proximal ureteral stones is around 81% when treated by either SWL or ureteroscopy (URS).Complication rates, most notably ureteral perforation and long-term complications of URS such as stricture formation rates, have been reduced to < 5%. Moreover, impacted ureteral calculi are more difficult to f...

INTRODUCTION Segmental ureterectomy with preservation of the kidney is a treatment option for the low grade urothelial carcinoma (LG-UC) in distal ureter that is not a candidate for endoscopic resection. Laparoscopic distal ureterectomy (LDU) with ureteral reimplantation is common in benign conditions (stenosis, iatrogenic lesion, endometriosis). However, it has been hardly described in maligna...

Seventy percent of ureteral stones are located at distal ureter. Effective and safe passage of distal ureter stones is mediated by observation or medical expulsive treatment. Most of stones located at distal ureter pass spontaneously under observation; however, some are complicated with urinary tract infection, hydronephrosis, and renal function disturbances. Spontaneous perforation of the uppe...

Urolithiasis is a significant and worldwide health problem. Ureteral stones account for approximately 20% of urolithiasis cases. 70% of those cases are with location of stone in the distal 1/3 rd of ureter hence known as Distal Ureteral Stones (DUS) or Lower Ureteral Stones (LUS). Recently certain drugs have been used as supplement for observation in an effort to improve spontaneous stone expul...

Duplex collecting systems are the most commonly encountered anomaly of the urinary system. Complete duplex system with an H shaped ureter is a very rare situation. There are only two reported H ureter cases in the literature. Herein, we aimed to present an H shaped ureter case, which was identified while performing ureterorenoscopy to a 48-year-old female patient due to a right distal ureteral ...

BACKGROUND Pyelocaliceal calculi flexible ureteroscopic approach raises problems related to operative time, associated morbidity and costs, especially by potential endoscope damage. METHODS 5 series, each of 20 patients with single pyelocaliceal lithiasis, were analyzed: Group I with calculi 1 cm fragmented to dust, Group II with calculi 1 cm with lithotripsy in fragments, Group III with calc...
