Resorbable clip migration resulting in ureteral obstruction and sepsis after laparoscopic pyeloplasty.

We report a rare complication of Lapra-Ty clip migration into the ureter with resultant obstruction and sepsis after dismembered laparoscopic pyeloplasty.

Need for ancillary procedures among patients undergoing tubeless percutaneous renal surgery for nephrolithiasis.

PURPOSE: We routinely perform percutaneous nephrolithotomy (PCNL) without the use of nephrostomy tubes. We examined the need for secondary surgery for the treatment of residual stones in patients who underwent both tubeless surgery and PCNL with tube placement. PATIENTS AND METHODS: We retrospectively reviewed the charts of 180 patients who underwent 186 percutaneous nephrolithotomies. Among them, 125 patients had tubeless surgery, and 61 had nephrostomy tubes. We compared the need for ancillary surgical procedures for residual stone disease in the two groups. RESULTS: A total of 99 patients (79%) without tubes and 25 (41%) of those with tubes were stone free after surgery. A total of 45 ancillary procedures were performed for residual stone disease, with 15% of the tubeless and 43% of the patients with tubes requiring a second procedure. Extracorporeal shockwave lithotripsy (SWL) was the most common ancillary procedure. CONCLUSIONS: Patients who are eligible for tubeless PCNL are unlikely to need a secondary procedure, and residual stones can most often be treated with SWL. Patients who required nephrostomy tubes had more complicated disease and a greater need for subsequent surgery.
