Purpose: Laparoendoscopic single-site donor nephrectomy (LESSDN) is a feasible and effective procedure because of its non-invasiveness and better cosmetic outcomes. However, there have been few multi-institutional studies conducted by multiple surgeons on LESSDN. We retrospectively compared the clinical data and outcomes between LESSDN and conventional laparoscopic donor nephrectomy (LDN) at multiple institutes in Japan., Materials and Methods: From 2009 to 2015, the clinical data of 223 donors who underwent LESSDN and 151 donors who underwent LDN were collected from 10 institutes. All LESSDNs were performed transperitoneally, whereas LDNs were performed transperitoneally (P-LDN) in 75 patients and retroperitoneally (R-LDN) in 76 patients., Results: In the LESSDN group, the single-incision site was pararectal in 155 (69.5%) patients and umbilical in 65 (29.1%) patients. Multiple surgeons (one to eight per institute) performed the LESSDN. No significant differences were observed between the three groups regarding estimated blood loss and warm ischemic time. The operative time was significantly shorter in the LESSDN group than in the R-LDN group (p = 0.018). No significant differences were observed regarding the rates of blood transfusion, open conversion, visceral injuries, and postoperative complications. Furthermore, no significant differences were observed regarding the dose of analgesic and the rate of delayed graft function. One patient required open conversion due to injury to the renal artery. Selection of LESS procedure was not an independent risk factor for the median serum creatinine level of above 1.27 mg/dL in recipients at 1 year after kidney transplantation., Conclusion: The results showed the technical feasibility of LESSDN compared with the standard LDNs in a multi-institutional and multi-surgeon setting. A few observed non-negligible complications and the significantly higher levels of serum creatinine in patients who underwent LESSDN indicate that this procedure should be employed cautiously when performed by surgeons without ample experience in performing LESS procedures.

Introduction: To evaluate safety and excellent cosmetic outcome with laparoendoscopic single-site surgery (LESS). In this study, we compared the usefulness and efficacy of LESS versus conventional laparoscopic surgery for the treatment of urachal remnants., Materials and Methods: We retrospectively reviewed the medical records of 20 consecutive patients who underwent either conventional laparoscopic surgery or LESS from January 2007 to February 2015 at Kansai Medical University Hospital. Ten patients underwent surgery using the standard laparoscopic 3-port technique, and 10 patients underwent LESS. The patients included 12 males and 8 females (mean age, 24.5 years; range, 10-68 years). The patients' characteristics, surgical data, and postoperative pain assessment results were retrospectively collected and analyzed., Results: The median operative time, pneumoperitoneal surgery time, and estimated blood loss did not differ between the LESS and conventional laparoscopic groups. However, the total incision length was longer in the conventional laparoscopic group than in the LESS group. The degree of pain at 2 to 5 days postoperatively according to the Wong-Baker FACES Pain Rating Scale was lower in the LESS group than in the conventional laparoscopic group (p < 0.05)., Conclusions: Less is a possible option in the surgical treatment for urachal remnants. In this very small cohort, there is no conversion to traditional laparoscopic surgery or open surgery. This technique is possibly feasible and may achieve less pain. Accumulation of surgical outcomes especially in safety and cosmesis is required to be an established method.

Objective: To determine whether conservative management of benign prostatic hyperplasia (BPH) is an appropriate option for patients with bladder stones., Methods: The study cohort comprised 34 men who underwent endoscopic bladder stone removal with subsequent conservative management of BPH, including watchful waiting and medical therapy (alpha-blocker ± dutasteride), between April 2006 and January 2014. We recorded BPH-related complications after stone removal and compared International Prostate Symptom Scores, quality of life scores, and postvoid residual urine volume before and after treatment. Cumulative BPH-related complication-free survival and the preoperative parameters associated with the occurrence of BPH-related complications were also analyzed., Results: Twenty-six patients (76.5%) treated with conservative management had no BPH-related complications, during a mean follow-up of 52.6 ± 30.9 months. Mean International Prostate Symptom Scores fell from 13.5 ± 7.1 before treatment to 9.7 ± 6.3 after treatment (P = .025). One of the 34 patients (2.9%) experienced recurrent urinary infections, 2 (5.9%) had urinary retention, and 6 (17.6%) developed recurrent bladder stones. The cumulative BPH-related complication-free survival was 97.0% at 1 year, 81.8% at 3 years, and 70.5% at 5 years. Six of the men (17.6%) underwent invasive intervention for BPH after occurrence of these complications. Prostate volume was the only preoperative parameter associated with the occurrence of complications after stone removal (P = .035)., Conclusion: Conservative management of BPH can be an appropriate treatment option in men with bladder stones and concurrent mild-to-moderate lower urinary tract symptoms., (Copyright © 2015 Elsevier Inc.
