Usage of ureteral DJ stent is very common in urology practise. There are some complications according to the increased usage of ureteral DJ stent in the literature. Stent fragmentation is a rare complication of ureteral DJ stent. In this study we present a 53-year-old male patient who had previous stone surgery and a ureteral DJ stent applied to our polyclinic with complaint of 3-months-long ri...

PURPOSE To evaluate the efficacy and safety of the ureteroscopic management of ureteral stones immediately after a first colic attack. MATERIALS AND METHODS We retrospectively analyzed the data of 226 patients with obstructive ureteral stones who underwent ureteroscopy with stone retrieval. The 67 patients in group A underwent ureteroscopy within 48 hours of admission to our emergency departm...

Introduction: Animal studies have shown that nicotine affects the peristalsis of the ureter. The aim of the study is to analyze the effect of smoking on spontaneous passage of distal ureteral stones.

Indications for the procedure included ureteral strictures of a 5.5 cm average ...

Endometriosis and urinary calculosis can co-occur. Clinical studies have shown that both painful and non-painful endometriosis in women are associated with enhanced pain and referred muscle hyperalgesia from urinary calculosis, but the mechanisms underlying this phenomenon are still poorly understood. The aim of this study was to develop an animal model adequate to explore this viscero-visceral...

PURPOSE To compare efficacy and safety between early extracorporeal shock wave lithotripsy (eESWL) and deferred ESWL (dESWL) in colic patients with ureteral stones and to investigate whether eESWL can play a critical role in improving treatment outcomes. MATERIALS AND METHODS A total of 279 patients who underwent ESWL for single radio-opaque ureteral stones of 5 to 20 mm in size were included...
