Laparoendoscopic single-site simultaneous bilateral nephrectomy: first reported case series.

Bilateral renal tumors in patients on dialysis are usually managed with bilateral nephrectomy. With traditional laparoscopy, this procedure requires the insertion of multiple trocars. Laparoendoscopic single-site surgery (LESS) uses a single umbilical incision to insert multiple instruments and is also employed for extraction of specimens. This technique appears especially useful for bilateral nephrectomy, since many access ports can be spared. We describe 5 cases of simultaneous bilateral radical nephrectomies performed at a single academic institution. We had no intraoperative complications and a mean operating time of 155 minutes. Four patients could be resected using this approach; one case was converted to a traditional laparoscopy. One case had a postoperative complication. We believe this technique is feasible, and can be accomplished with acceptable morbidity and ade-quate operative time.

Functional outcomes and quality of life after transobturatory slings: hand - made vs. commercial slings.

Surgical correction is the most efficient treatment for stress urinary incontinence (SUI), and transobturator sling (TO) has optimal results. The high cost of commercially available sling kits makes it difficult the access in most Brazilian public health services. Hand-made polypropylene slings, on the other hand, have been previously reported. The aim of the present study was to compare the effectiveness and safety of commercial vs. hand-made polypropylene mesh slings. Data from 57 women who underwent consecutive TO sling surgery to treat SUI were pros-pectively collected between 2012 and 2014, and divided in two groups for further comparison. In Group-1, 31 women underwent surgery with commercial slings. In Group-2, 26 women underwent hand-made polypropylene slings. Women were compared according to epidemiological data, perioperative evaluation, quality of life, urodynamic study, cure and complication rates. Results were objectively (stress test with Valsalva maneuver, with at least 200mL vesical repletion) and subjectively evaluated by the Patient Global Impression of Improvement(PGI-I), Visual Analog Scale (VAS) and ICIQ-SF. Success was defined as PGI-I, VAS and negative stress test. Group-1 (n=31) and Group-2 (n=26) had a mean age of 60 vs. 58years (p=0.386). All de-mographic data were similar. The mean VLPP was 75.6cmH2O vs. 76.6cmH2O (p=0.88). The mean follow-up was 24.3 vs. 21.5months (p=0.96). Success rates were 74.2% vs. 80.2% (p=0.556), with ICIQ-SF variation of 12.6 vs.15.5 (p=0.139) and PGI-I of 71% vs. 80% (p=0.225). There was only one major complication (urethrovaginal fistula in Group-1). In conclusion, handmade and commercial slings have similar effectiveness and safety. The manufacture technique has important key-points stated in the present manuscript.
