Five-Year Single Center Experience for Retroperitoneoscopic Ureterolithotomy.

Abstract Introduction: Narrow working space is a major problem to overcome during retroperitoneoscopic ureterolithotomy. We evaluated initial 5 years experience of retroperitoneoscopic ureterolithotomy for large impacted upper ureteral calculi. Patients and Methods: Between January 2011 and December 2015, a total of 37 consecutive patients were evaluated. A 12-mm camera port at middle of midaxillary line and two 5-mm working ports in posterior axillary line were created. The stone was extracted through the site of camera trocar. A Double-J catheter (DJC) was placed antegradely by four steps (elevating of the proximal shaft, introducing the end of curl, advancing, and twisting) during retroperitoneoscopic ureterolithotomy. A knotless unidirectional barbed suture was applied to the incision site of the ureter in all cases. All patients were followed up at 2 weeks after discharge to remove a DJC and at 6 weeks after discharge to evaluate urinary drainage with intravenous urography. Results: The mean ± standa...
