To present our experience of combining transperitoneal mini-laparoscopic pyeloplasty (mini-LP) and concomitant ureteroscopy-assisted pyelolithotomy (U-P) for ureteropelvic junction obstruction (UPJO) complicated by renal caliceal stones in the same session.Between May 2007 December 2011, mini-LP U-P was performed nine patients with UPJO ipsilateral stones. Stone location burden were preoperatively assessed. After pyelotomy appropriate length (about 4 mm), a 16-Fr catheter sheath replaced uppermost or lowermost laparoscopic trocar introduced directly into pelvis under guidance guide wire vision. A 7.5F rigid ureteroscopy passed through plevis. Intracorporeal lithotripsy and/or pressure irrigation via pump used stone removal. Subsequently, standard fashion. Postoperative imaging assessed.The calculi sizes ranged from 2 to 11 mm (mean, 7.1 mm) an average 3 per patient removed (range, 1 6 stones). Complete clearance confirmed postoperative achieved all patients. Mean operative time 210 minutes, estimated blood loss 20 mL. hospital stay 5 days (4-7). Stent after 4-8 weeks. No intraoperative complications noted during mean follow-up 18.5 months 24 months).Mini-LP are simple effective alternatives simultaneous management coexisting
