Single-port Laparoscopic Retroperitoneal Surgery Using a Modified Single-Port Device in Urology.

OBJECTIVES:To investigate the use of a flexible instrument platform in performing single-port laparoscopic retroperitoneal urologic surgeries and to verify the safety and feasibility of these surgeries.METHODS:The homemade instrument platform consisted of two control loops and a powder-free surgical glove to form multichannels. 56 patients underwent this kind of single-port surgery for different urologic diseases, including radical nephrectomy in 31 patients, nephroureterectomy in 7 patients, partial nephrectomy in 8 patients, living donor nephrectomy in 4 patients, adrenalectomy in 3 patients, renal cyst surgery in 2 patients and ureterolithotomy in 1 patient.RESULTS:All surgeries were completed successfully with no switch to conventional laparoscopic or open surgery. The mean hospital stay was 13.13 days (range 6-36). All patients were satisfied without major complications.CONCLUSIONS:Retroperitoneal laparoendoscopic single-site surgery using our cost-effective homemade instrument platform appears to be a feasible and safe surgical strategy to perform retroperitoneal laparoscopic urologic surgery.
