Synchronous bilateral laparoendoscopic single-site urological surgeries via the umbilicus: a report of 2 cases

ObjectiveTo describe two cases of bilateral transumbilical laparoendoscopic single-site(LESS) surgeries in a single operative session and assess the safety, feasibility and efficacy.MethodsOne patient underwent right ureterolithotomy and left varicocelectomy, and the patient was performed with right simple nephrectomy for nonfunctioning kidney due to ureteral calculus and left ureterolithotomy using a novel multichannel TriPort™ via a single 2–3 cm transumbilical incision.ResultsThe right-side ureterolithotomy and left-side varicocelectomy were finished in 229 minutes, with a total estimated blood loss of 50 ml. The right-side simple nephrectomy and left-side ureterolithotomy in the other patient were finished in 340 minutes, with a total estimated blood loss of 100 ml. There were no major complications. At the latest follow-up, both patients remained symptom-free and there were no evidences of recurrence. Both of them were delighted for the single scar.ConclusionSynchronous LESS urologic procedure via a single umbilical incision is technically feasible, safe and efficacious with a promising potential.
