RATIONALE In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal funct...

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 ...

BACKGROUND AND OBJECTIVES Studies of patients with benign pathologic lesions who underwent laparoscopic radical nephroureterectomy (RNU) with preoperative suspicion of upper urinary tract urothelial carcinoma are lacking. The aim of this retrospective cross-sectional study was to evaluate the incidence of benign pathologic lesions on laparoscopic RNU for upper urinary tract tumors that are pres...

BACKGROUND AND PURPOSE The present study was carried out to compare the efficacy of ESWL treating radiolucent ureteric calculi visible in the ureter after application of contrast media. MATERIAL AND METHODS Medical records of 47 patients who had verified ureteric calculi by intravenous urography and retrograde pyelography were included in this study.

Pneumatic Lithotripsy (PL) is considered effective in fragmenting hard stones, and this procedure can also be performed transurethrally percutaneously on large stones. This study aimed to see the percentage of Stone Free Rate (SFR) by administering force diuretics ureteral stones that were crushed using PL. Previous studies have found intravenous loop diuretic administration effective, safe, ef...
