Abstract
BACKGROUND: The management of complete staghorn stones remains a challenge for urologists, owing to the high stone burden, low stone free rate, and high rate of complications. Hence, we aimed to evaluate the outcomes of a technique involving combination laparoscopy and nephrolithotomy in the same session in patient with complete staghorn stones and poor performance status. METHODS: We retrospectively evaluated seven patients with complete staghorn stones who underwent a combination of laparoscopy and nephrolithotomy in the same session in our center between December 2016 and October 2019. The surgical technique was as follows. Through a four-port transperitoneal laparoscopic approach, the kidney was mobilized after complete dissection of the renal pedicle. The renal pelvis was then incised with a cold scalpel. A nephroscope was inserted into the renal collecting system through both a laparoscopic port and the renal pelvis incision. This method enabled visualization of and access to almost all calyces for clearing the stones from the affected kidneys in a hand-assisted manner which a hand was inserted in the peritoneal cavity. The outcome data included the stone-free rate, short-term and long-term complication rates, and stone recurrence rate. RESULTS: The stone free rate was 85.70% (6/7). No patients had sepsis or required blood transfusion perioperatively, and no major short-term complications occurred. After 24.00 (15.00, 48.00) months' follow-up, no patients had long-term complications, and only one patient had stone recurrence. CONCLUSION: The technique of combining laparoscopy and nephrolithotomy in the same session was an effective and safe treatment for patients with complete staghorn stones and poor performance status. The method was scarcely affected by the stone burden and morphology, had a satisfactory stone free rate, and resulted in no major complications, particularly life-threatening sepsis. It might be an option for such patients.
