Bilateral hand-assisted retroperitoneoscopic nephroureterectomy (HARN) in the spread-eagle position for dialysis patients-low midline HARN in a completely supine position

A modified single mini-incision complete urinary tract exenteration for urothelial carcinoma in dialysis patients

Objective. To present our experience with single mini-incision complete urinary tract exenteration (CUTE) for female dialysis patients suffering from urothelial carcinoma (UC). Patients and Methods. Institutional review board approval was obtained. From 2005 through 2012, 14 female dialysis patients with UC underwent single mini-incision CUTE, in combination with radical hysterectomy and bilateral salpingo-oophorectomy. All were placed in the modified dorsal lithotomy position without repositioning. An infraumbilical midline mini-incision was made. Bilateral nephroureterectomy was first performed entirely extraperitoneally, followed by radical cystectomy with removal of the uterus and ovaries transperitoneally. Results. All procedures were done successfully without major complications. The median operative time was 242.5 minutes, and estimated blood loss was 500 mL. The median time to oral intake was 2 postoperative days; the median hospital stay was 11 days. Ten patients remained cancer-free at a median follow-up of 46.5 months; six patients were confirmed as having preoperatively undetectable UC or renal cell carcinoma, even after reviewing preoperative computed tomography. Conclusions. This modified technique provides a time-saving complete urinary tract extirpation to eliminate preoperatively undetectable malignancy, reduce metachronous recurrences, and avert perioperative complications associated with pneumoperitoneum and repositioning. Good cancer control and early convalescence can mutually be achieved in experienced hands.

Hand-assisted retroperitoneoscopic nephroureterectomy with bladder cuffing after preperitoneal and retroperitoneal perivesical ballooning

Purpose

We aimed to describe the surgical technique of hand-assisted retroperitoneoscopic nephroureterectomy (HARNU) with bladder cuffing after preperitoneal and retroperitoneal perivesical ballooning.

Materials and Methods

From March 2008 to September 2012, we performed HARNU and open bladder cuffing in 28 consecutive series of patients with upper urinary tract urothelial carcinoma. We performed HARNU according to the following procedure: (1) a camera port incision was made on the posterior axillary line; (2) multiple, repeated, preperitoneal and retroperitoneal ballooning was performed on both the posterior axillary line and in the umbilicus; (3) a 7.0 cm skin incision was made from the suprapubic to the lower inguinal with the balloon present in the extraperitoneal area; (4) hand-assisted laparoscopic retroperitoneal nephroureterectomy; (5) cessation of gas insufflation; and (6) extravesical cuffing as an open surgical procedure.

Results

The mean estimated blood loss was 250 mL. The mean operation time was 240 minutes. The mean time to oral intake and ambulation was 1.0 day and two days, respectively. As for postoperative complications due to the hand-assisted device, one patient developed febrile urinary tract infection within three weeks postoperatively and was hospitalized again to receive parenteral antibiotics.

Conclusions

We made a low Gibson incision for a route for the hand-assisted procedure as well as a window for open surgery in dissecting the distal ureter and extracting the surgical specimens. Thus, our results indicate that the HARNU might be a feasible surgical modality.
