Conventional Laparoscopic Versus Laparoendoscopic Single Site Donor Nephrectomy in Living Donor Kidney Transplantation
Study Details
Study Description
Brief Summary
Laparoscopic nephrectomy (removal of the kidney) is the most common procedure for people donating a kidney to be used for living donor kidney transplantation. Laparoscopic donor nephrectomy (LDN) was a great advance in the field of living donor kidney transplantation due to the many advantages it offers over open nephrectomy, including significantly shorter hospitalization and recovery time, and significantly improved cosmetic result related to the nephrectomy scar(s). More recently, a new procedure has been introduced to the field of laparoscopic nephrectomy, called laparoendoscopic single site donor nephrectomy (LESS-DN). In the LESS-DN procedure, a single natural orifice (the umbilicus or belly button) is used as the single incision site through which the entire donor nephrectomy is performed. The LESS-DN procedure may further decrease donor morbidity by further decreasing length of stay, lessening recovery time, and improving satisfaction with the surgical scar. The investigators propose to evaluate conventional LDN versus a LESS-DN in a randomized, controlled trial in living kidney donors. The investigators will compare operative times and intra-operative donor management, intra- and post-operative complications, pain scores, analgesic requirements, length of stay, recovery parameters, surgical scar satisfaction, and function and survival of the transplanted kidney for the two groups of subjects: (1) the group that has the conventional laparoscopic donor nephrectomy; and, (2) the group that has the laparoendoscopic single site donor nephrectomy.

Outcome Measures
Primary Outcome Measures
- The Primary End Point of the Study Was the Mean/Median Number of Days Postsurgery Required for Each Group to Return to 100% Functioning Capacity. [1 year]
The Primary Endpoint of the Study Will be Patient Self-reported "Return to 100%", as Measured by the Number of Days Post-surgery That the Patient Reports His or Her Return to 100% Functioning Capacity.
Secondary Outcome Measures
- Days on Oral Pain Medication After Discharge [2 months]
- Days Before Going Back to Work [2 months]
- Days to Normal Day-to-day Activities [2 months]
- Recovered by 2 Months After Donation [2 months]
