Summary
Laparoendoscopic single-site (LESS) pyeloplasty shows a higher complication rate early in the learning curve. However, experienced surgeons achieve similar complication rates to standard laparoscopic pyeloplasty within a few cases.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Surgical Education
Background:
- Laparoendoscopic single-site (LESS) pyeloplasty is an advanced surgical technique.
- Understanding the initial learning curve and associated morbidity is crucial for adoption.
Purpose of the Study:
- To evaluate the initial 30-day complication rates of LESS pyeloplasty.
- To assess the learning curve and expected morbidity for this procedure.
- To compare early outcomes with conventional laparoscopic pyeloplasty.
Main Methods:
- Retrospective chart review of 28 patients undergoing LESS pyeloplasty by a single surgeon.
- Analysis of complications occurring within 30 days post-surgery.
Main Results:
- The mean operative time was 197 minutes.
- Seven patients (25%) experienced eight complications, including four requiring nephrostomy tubes and two with urine leaks.
- Complications were concentrated in the first ten cases (71%), with only two in the subsequent 18 patients.
Conclusions:
- LESS pyeloplasty presents technical challenges, potentially leading to higher early complication rates.
- The complication rate becomes comparable to standard laparoscopic pyeloplasty after a learning period of fewer than ten cases.
- Further follow-up is necessary to establish long-term success rates.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
