Abstract: Robotic-assisted radical cystectomy (RARC) is a less invasive means of performing the radical cystectomy operation, which holds promise for improved patient morbidity. We review the history, technique and current literature pertaining to RARC and place the current results in context with the open procedure. All articles regarding RARC found in PubMed after January 2000 were examined. We selected articles that appeared in high-impact journals, had large patient population size (> 80 patients), or were novel in technique or findings. We chose key laparoscopic articles to give reference to the history in transition to robotic radical cystectomy. In addition, we chose classic articles from open radical cystectomy to give reference regarding the newer robotic perioperative outcomes. Studies suggest that a 20-patient learning curve is needed to reach an operative time of 6.5 h, with 30 surgeries performed to reach lymph node counts in excess of 20 (International Robotic Cystectomy Consortium). The only randomized surgical trial comparing open and robotic techniques showed equivalent lymph node yield, which may be surgeon and volume dependent. Literature demonstrates lower estimated blood loss, transfusion rates, early return of bowel function and decreased complications in early small series. RARC and urinary diversion are still early in development and limited to centers with extensive robotic experience and volume, although adoption of the robotic approach is becoming more common. Early studies have shown promise to reduce complications with equivalent oncologic results.

Abstract: Gender differences are increasingly recognized as important in numerous diseases and found to be relevant in various cancer entities. While a larger number of manuscripts on gender effects in gastro-intestinal and pulmonary neoplasms have been published, urological malignancies involving men and women alike seem less studied in this regard. The present analysis aimed at describing the role of gender effects in general oncological and uro-oncological research and is the first such bibliometrical analysis. The electronic database MEDLINE was searched for relevant medical subject headings from January 1991 to December 2011. Publication types, publishing journal and impact factors were identified. Trends were assessed by linear regression. The numbers of annual publications on all major tumour entities and on urological malignancies increased similarly. While the portion of publications on gender effects was below 1 % for each tumour entity, the annual increase of novel publications on gender effects was significant in most and prominent in pulmonary (1.87, 95 % CI 1.11-2.63; < 0.0001) and colorectal neoplasms (2.16, 95 % CI 1.49-2.82; < 0.0001). While the annual increase of novel publications on gender effects was significant in bladder cancer (0.33, 95 % CI 0.11-0.54; 0.005), it failed level of significance in renal cell cancer (0.25, 95 % CI -0.19-0.24; 0.82). While the overall role of gender effect seems small in general oncological research, it is increasing steadily. In uro-oncological research, such trend is also visible in bladder but not in renal cell cancer. Respective awareness on importance of gender effects should be raised.

Abstract: To assess the efficacy and safety of thulium laser versus standard transurethral resection of the prostate (TURP) for treating patients with benign prostatic obstruction. A systematic search of the electronic databases, including Medline, Embase, Web of Science, and The Cochrane Library, was performed up to February 1, 2014. The pooled estimates of demographic and clinical baseline characteristics, perioperative variables, complications, and postoperative efficacy including International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax), and postvoid residual (PVR) were calculated. Seven trials assessing thulium laser versus standard TURP were considered suitable for meta-analysis including four randomized controlled trials (RCTs) and three non-RCTs. Compared with TURP, although thulium laser prostatectomy (TmLRP) needed a longer operative time [weighted mean difference (WMD) 8.18 min; 95 % confidence interval (CI) 1.60-14.75; P = 0.01], patients having TmLRP might benefit from significantly less serum sodium decreased (-3.73 mmol/L; 95 % CI -4.41 to -3.05; P < 0.001), shorter time of catheterization (WMD -1.29 days; 95 % CI -1.95 to -0.63; P < 0.001), shorter length of hospital stay (WMD -1.83 days; 95 % CI -3.10 to -0.57; P = 0.005), and less transfusion (odds ratio 0.09; 95 % CI 0.02-0.41; P = 0.002). During the 1, 3, and, 12 months of postoperative follow-up, the procedures did not demonstrate a significant difference in IPSS, QoL, Qmax, and PVR. TmLRP had a similar efficacy to standard TURP in terms of IPSS, QoL, Qmax, and PVR, and offered several advantages over TURP in terms of blood transfusion, serum sodium decreased, catheterization time, and hospital stay, while TURP was superior in terms of operation duration. Well-designed multicentric/international RCTs with long-term follow-up are still needed.
