Robotic urological surgery is one of the most significant urological developments in recent years. It allows for greater precision than laparoscopic methods while retaining quicker recovery time and reduced morbidity over classical open surgical techniques. For children, where the room for error is already reduced because of smaller anatomy, it takes on even more importance for urologists.  As a result, robotic surgery is rightly considered one of the most exciting contemporary developments in pediatric urology.

PurposeTo identify prognostic factors of failure in patients undergoing perineal urethrostomy (PU) with Blandy technique, with inverted U-shaped perineal flap.MethodsThis is a retrospective study of PU of non-oncological causes (2001–2017). Data of age, BMI, history of diabetes mellitus, etiology of urethral stricture, type of stricture, previous surgeries, dilatation and suprapubic catheter were collected. Failure was defined as the need for any instrumentation after surgery. Variables were analyzed by Cox regression and Kaplan–Meier curves were used for survival analysis.ResultsA total of 115 PU were performed. Median age was 61 years (IQR 53–68) and BMI 27.9 (IQR 25–30.9). The most frequent etiologies were: lichen sclerosus (30.4%), iatrogenic (27%), and idiopathic (25.7%). 62.6% had panurethral stricture. There were no complications in 73%. Clavien I complications occurred in 25.2%, Clavien II in 0.9% and Clavien IVa in 0.9%. The overall success rate was 51.3% with a median follow-up of 71 months. In the last 8 years, it was 75%. In the multivariate analysis, we found that age (p = 0.01), BMI (p = 0.01), date of surgery (p = 0.01), and suprapubic catheter (p = 0.003) were predictive variables. The voiding satisfaction rate was 88.7%.ConclusionsPU with Blandy technique is a surgery with low morbidity. During the entire study period, it had a failure rate of 48.7% but the failure rate decreased to 25% over the last 8 years. Age, BMI, date of surgery and suprapubic catheter are the most important prognostic factor of failure.

Concerns have been raised about the safety of surgery for stress urinary incontinence and pelvic organ prolapse using transvaginal mesh. We assessed adverse outcomes after first, single mesh procedures and comparable non-mesh procedures. We did a cohort study of women in Scotland aged 20 years or older undergoing a first, single incontinence procedure or prolapse procedure during 1997–98 to 2015–16 identified from a national hospital admission database. Primary outcomes were immediate postoperative complications and subsequent (within 5 years) readmissions for later postoperative complications, further incontinence surgery, or further prolapse surgery. Poisson regression models were used to compare outcomes after procedures carried out with and without mesh. Between April 1, 1997, and March 31, 2016, 16 660 women underwent a first, single incontinence procedure, 13 133 (79%) of which used mesh. Compared with non-mesh open surgery (colposuspension), mesh procedures had a lower risk of immediate complications (adjusted relative risk [aRR] 0·44 [95% CI 0·36–0·55]) and subsequent prolapse surgery (adjusted incidence rate ratio [aIRR] 0·30 [0·24–0·39]), and a similar risk of further incontinence surgery (0·90 [0·73–1·11]) and later complications (1·12 [0·98–1·27]); all ratios are for retropubic mesh. During the same time period, 18 986 women underwent a first, single prolapse procedure, 1279 (7%) of which used mesh. Compared with non-mesh repair, mesh repair of anterior compartment prolapse was associated with a similar risk of immediate complications (aRR 0·93 [95% CI 0·49–1·79]); an increased risk of further incontinence (aIRR 3·20 [2·06–4·96]) and prolapse surgery (1·69 [1·29–2·20]); and a substantially increased risk of later complications (3·15 [2·46–4·04]). Compared with non-mesh repair, mesh repair of posterior compartment prolapse was associated with a similarly increased risk of repeat prolapse surgery and later complications. No difference in any outcome was observed between vaginal and, separately, abdominal mesh repair of vaginal vault prolapse compared with vaginal non-mesh repair. Our results support the use of mesh procedures for incontinence, although further research on longer term outcomes would be beneficial. Mesh procedures for anterior and posterior compartment prolapse cannot be recommended for primary prolapse repair. Both vaginal and abdominal mesh procedures for vaginal vault prolapse repair are associated with similar effectiveness and complication rates to non-mesh vaginal repair. These results therefore do not clearly favour any particular vault repair procedure. None.

Complications of surgical mesh procedures have led to legal cases against manufacturers worldwide and to national inquiries about their safety. The aim of this study was to investigate the rate of adverse events of these procedures for stress urinary incontinence in England over 8 years. This was a retrospective cohort study of first-time tension-free vaginal tape (TVT), trans-obturator tape (TOT) or suprapubic sling (SS) surgical mesh procedures between April 2007 and March 2015. Cases were identified from the Hospital Episode Statistics database. Outcomes included number and type of procedures, including those potentially confounded by concomitant procedures, and frequency, nature and timing of complications. 92,246 first-time surgical mesh procedures (56,648 TVT, 34,704 TOT, 834 SS and 60 combinations) were identified, including 68,002 unconfounded procedures. Peri-procedural and 30-day complication rates in the unconfounded cohort were 2.4 [2.3–2.5]% and 1.7 [1.6–1.8]% respectively; 5.9 [5.7–6.1]% were readmitted at least once within 5 years for further mesh intervention or symptoms of complications, the highest risk being within the first 2 years. Complication rates were higher in the potentially confounded cohort. The complication rate within 5 years of the mesh procedure was 9.8 [9.6:10.0]% This evidence can inform future decision-making on this procedure.

PurposeFor the last 20 years, the predominant robot used in laparoscopic surgery has been Da Vinci by Intuitive Surgical. This monopoly situation has led to rising costs and relatively slow innovation.

AbstractObjectivesTo compare the effectiveness and safety of surgical interventions for women with stress urinary incontinence.DesignSystematic review and network meta-analysis.Eligibility criteria for selecting studiesRandomised controlled trials evaluating surgical interventions for the treatment of stress urinary incontinence in women.MethodsIdentification of relevant randomised controlled trials from Cochrane reviews and the Cochrane Incontinence Specialised Register (searched May 2017), which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Medline In-Process, Medline Epub Ahead of Print, CINAHL, ClinicalTrials.gov, and WHO ICTRP. The reference lists of relevant articles were also searched. Primary outcomes were “cure” and “improvement” at 12 months, analysed by means of network meta-analyses, with results presented as the surface under the cumulative ranking curve (SUCRA). Adverse events were analysed using pairwise meta-analyses. Risk of bias was assessed using the Cochrane risk of bias tool. The quality of evidence for network meta-analysis was assessed using the GRADE approach.Results175 randomised controlled trials assessing a total of 21 598 women were included. Most studies had high or unclear risk across all risk of bias domains. Network meta-analyses were based on data from 105 trials that reported cure and 120 trials that reported improvement of incontinence symptoms. Results showed that the interventions with highest cure rates were traditional sling, retropubic midurethral sling (MUS), open colposuspension, and transobturator MUS, with rankings of 89.4%, 89.1%, 76.7%, and 64.1%, respectively. Compared with retropubic MUS, the odds ratio of cure for traditional sling was 1.06 (95% credible interval 0.62 to 1.85), for open colposuspension was 0.85 (0.54 to 1.33), and for transobtrurator MUS was 0.74 (0.59 to 0.92). Women were also more likely to experience an improvement in their incontinence symptoms after receiving retropubic MUS or transobturator MUS compared with other surgical procedures. In particular, compared with retropubic MUS, the odds ratio of improvement for transobturator MUS was 0.76 (95% credible interval 0.59 to 0.98), for traditional sling was 0.69 (0.39 to 1.26), and for open colposuspension was 0.65 (0.41 to 1.02). Quality of evidence was moderate for retropubic MUS versus transobturator MUS and low or very low for retropubic MUS versus the other two interventions. Data on adverse events were available mainly for mesh procedures, indicating a higher rate of repeat surgery and groin pain but a lower rate of suprapubic pain, vascular complications, bladder or urethral perforation, and voiding difficulties after transobturator MUS compared with retropubic MUS. Data on adverse events for non-MUS procedures were sparse and showed wide confidence intervals. Long term data were limited.ConclusionsRetropubic MUS, transobturator MUS, traditional sling, and open colposuspension are more effective than other procedures for stress urinary incontinence in the short to medium term. Data on long term effectiveness and adverse events are, however, limited, especially around the comparative adverse events profiles of MUS and non-MUS procedures. A better understanding of complications after surgery for stress urinary incontinence is imperative.Systematic review registrationPROSPERO CRD42016049339.

In the field of urology, robotic surgery has gained rapid and wide acceptance as a standard surgical approach in the majority of major surgeries over the last decade. To date, the da Vinci surgical system has been the dominant platform in robotic surgery; however, several newly developed robotic systems have recently been introduced in routine clinical practice. Of these, hinotori, the first made-in-Japan robotic system, is characterized by various unique and attractive features different from the existing system, and the use of this system has gradually increased mainly in urologic cancer surgeries, including radical prostatectomy, partial nephrectomy, radical nephrectomy, and radical nephroureterectomy. This review initially describes detailed characteristics of hinotori, then summarizes the early experience with urologic cancer surgeries using hinotori at our institution, and finally discusses the future prospects of robotic surgery using hinotori, considering problems associated with the use of this robotic system.

Twenty years after it was introduced, robotic surgery has become more commonplace in urology – we examine its current uses and controversies

Robot-assisted surgery has transformed urology, but widespread adoption remains limited by the high cost, complex setup, and rigid system design. This prospective single-center study evaluates the safety and efficacy of the novel modular Carina in 19 upper and lower urinary tract surgeries. All cases were completed robotically without conversion, with one major complication . For partial nephrectomy (PN), median operative time (OT) was 120 min with 50 mL estimated blood loss (EBL), including one off-clamp PN completed in 77 min (EBL: 50 mL). Pyeloplasty had a median OT of 105 min (EBL: 50 mL), while radical prostatectomy (RP) achieved a median OT of 150 min (EBL: 50 mL). Radical cystectomy was completed in 301 min without major complications, and an uncomplicated postoperative course . Median docking times were 5 and 8 min for upper and lower tract surgeries, with negative margins and preserved renal function in all PN, and social continence post-RP. The Carina system demonstrates procedural safety and feasibility in complex urological procedures. The modular design may enhance workflow and space utilization, suggesting the potential for promising tool and broader clinical applications. Further validation with larger sample sizes and long-term follow-up is needed.
