Ischemic priapism Low flow (ischemic) priapism is a penile erection persisting beyond four hours unrelated to sexual interest or stimulation. This type of priapism causes a compartment syndrome of the corporal bodies with progressive hypoxia, hypercarbia and acidosis. Clinically, it is typified by progressive penile pain with rigid, tender corporal bodies and soft glans penis and corpus spongio...

Purpose: High intra-renal pressures during flexible ureteroscopy have been associated with adverse renal tissue changes as well pyelovenous backflow. Our objective was to investigate the effect of various on histologic and fluid extravasation simulated ureteroscopy. Materials Methods: Twenty-four juvenile pig kidneys intact ureters were cannulated an Olympus ureteroscope without a ureteral acce...

Although stone free rates were quite high in both size categories (95% versus 89%, respectively), retreatment rates were significantly higher in the larger stone group (45% versus 11%, respectively), translating into an efficiency quotient of 81 for treatment of stones ≤ 7 mm and 58 for stones > 7mm. Although this size cutoff was chosen randomly, it provides a reasonable algorithm to guide trea...

Indication has led ureteroscopy to be a worldwide technique, with the expected appearance of multiple complications. The ureteral avulsion is an uncommon severe urological complication of ureteroscopy (URS). Surgery in patients with a total ureteral loss is a demanding challenge for urologist. It requires usually immediate open or laparoscopic intervention. This case report was to present the t...

INTRODUCTION The prevalence of urolithiasis is increasing worldwide and is causing significant morbidity and cost to the healthcare systems. While ureteroscopy (URS) has been established as a treatment option, our review highlights the expanding role of URS for the management of more complex stones and patients in the modern era. MATERIAL AND METHODS Ureteroscopy has shown to have good outcom...

BACKGROUND To evaluate the feasibility of flexible ureteroscopy training by using isolated porcine kidneys and ureters in vitro. METHODS Twenty young urologists were randomly divided into four groups. Overall performance was assessed based on a global rating scale, pass/fail rating, total time to complete task, learning curve, incidence of trauma, and perforations. The effect of training was ...

Kidneys are very common sites of cysts in the human body, prevalence of renal cysts was estimated to be about 10% in the general population and the incidence increases with age. Parapelvic and peripelvic cysts grow near renal collecting system; these types of cysts are most likely to be symptomatic. There are a number of reports describing successful laser incision drainage of parapelvic cysts ...

OBJECTIVES The objectives of this prospective study are to present our experience with retrograde intrarenal surgery (RIRS), and to analyze its results and complications. MATERIAL AND METHODS 150 patients with renal stones were treated with RIRS. 111 cases showed single stones whilst multiple stones were observed in 39 cases. The mean size was 19.12mm (r: 5-74). Success rate was defined as th...
