RESUMO

Radical prostatectomy is a commonly adopted treatment for localized/locally advanced prostate cancer in men with a life expectancy of ten years or more. Robotic-assisted radical prostatectomy (RARP) is comparable to open radical prostatectomy on cancer control and complication rates; however, new evidence suggests that RARP may have better functional outcomes, especially with respect to urinary incontinence and erectile dysfunction. Some of the surgical steps of RARP are not adequately described in published literature and, as such, may have an impact on the final outcomes of the procedure. We organized a Brazilian experts' panel to evaluate best practices in RARP. The confection of the recommendations broadly involved: selection of the experts; establishment of working groups; systematic review of the literature and elaboration of a questionnaire; and construction of the final text with the approval of all participants. The participants reviewed the publications in English from December 2019 to February 2020. A one-round Delphi technique was employed in 188 questions. Five reviewers worked on the final recommendations using consensual and non-consensual questions. We found 59.9% of questions with greater than 70% agreement that were considered consensual. Non-consensual questions were reported according to the responses. The recommendations were based on evidence-based literature and individual perceptions adapted to the Brazilian reality, although some issues remain controversial. We believe that these recommendations may help urologists involved in RARP and hope that future discussions on this surgical procedure may evolve over the ensuing years.

RESUMO

OBJECTIVE: to describe our experience with a minimally invasive approach for persistent vesicourethral anastomotic leak (PVAL) after Laparoscopic Radical Prostatectomy (LRP). METHODS: from 2004 to 2011, two surgeons performed LRP in 620 patients. Ten patients had PVAL, with initially indicated conservative treatment, to no avail. These patients underwent a minimally invasive operation, consisting of an endoscopically insertion of two ureteral catheters to direct urine flow, fixed to a new urethral catheter. We maintained the ureteral catheters for seven days on average to complete resolution of urine leakage. The urethral catheter was removed after three weeks of surgery. RESULTS: the correction of urine leakage occurred within a range of one to three days, in all ten patients, without complications. There were no stenosis of the bladder neck and urinary incontinence on long-term follow-up. CONCLUSION: the study showed that PVAL after laparoscopic radical prostatectomy can be treated endoscopically with safety and excellent results. OBJETIVO: descrever nossa experiência com uma abordagem minimamente invasiva para fístula de anastomose vesicouretral persistente (FAVP) após prostatectomia radical laparoscópica (PRL). MÉTODOS: de 2004 a 2011, 620 pacientes foram submetidos à prostatectomia radical laparoscópica realizada por dois cirurgiões. Dez pacientes apresentaram FAVP e o tratamento conservador foi inicialmente indicado sem sucesso. Esses pacientes foram submetidos a uma reoperação minimamente invasiva, por via endoscópica, com inserção de dois cateteres ureterais para direcionar o fluxo urinário, fixados a um novo cateter uretral. Os cateteres ureterais foram mantidos por sete dias, em média, até a completa resolução do vazamento de urina. O cateter uretral foi removido após três semanas da cirurgia. RESULTADOS: a correção do vazamento de urina ocorreu dentro de um intervalo de um a três dias em todos os dez pacientes, sem complicações. Não foram observadas estenose de colo vesical ou incontinência urinária após acompanhamento em longo prazo. CONCLUSÃO: o estudo mostrou que a FAVP após a prostatectomia radical laparoscópica pode ser tratada por via endoscópica com segurança e excelentes resultados.

RESUMO

BACKGROUND: Robotic-assisted radical prostatectomy (RALP) is a minimally invasive procedure that could have a reduced learning curve for unfamiliar laparoscopic surgeon. However, there are no consensuses regarding the impact of previous laparoscopic experience on the learning curve of RALP. We report on a functional and perioperative outcome comparison between our initial 60 cases of RALP and last 60 cases of laparoscopic radical prostatectomy (LRP), performed by three experienced laparoscopic surgeons with a 200+LRP cases experience. MATERIALS AND METHODS: Between January 2010 and September 2013, a total of 60 consecutive patients who have undergone RALP were prospectively evaluated and compared to the last 60 cases of LRP. Data included demographic data, operative duration, blood loss, transfusion rate, positive surgical margins, hospital stay, complications and potency and continence rates. RESULTS: The mean operative time and blood loss were higher in RALP (236 versus 153 minutes, p<0.001 and 245.6 versus 202ml p<0.001). Potency rates at 6 months were higher in RALP (70% versus 50% p=0.02). Positive surgical margins were also higher in RALP (31.6% versus 12.5%, p=0.01). Continence rates at 6 months were similar (93.3% versus 89.3% p=0.43). Patient's age, complication rates and length of hospital stay were similar for both groups. CONCLUSIONS: Experienced laparoscopic surgeons (ELS) present a learning curve for RALP only demonstrated by longer operative time and clinically insignificant blood loss. Our initial results demonstrated similar perioperative and functional outcomes for both approaches. ELS were able to achieve satisfactory oncological and functional results during the learning curve period for RALP.

RESUMO

OBJECTIVE: The reproducibility of high-volume published series of laparoscopic radical prostatectomy (LRP) is still debatable. Many questions about its implementation, safety, and number of procedures required to achieve competence and improvement of outcomes with the technique remain unclear, and a learning curve study is crucial to investigate the acceptable performance of this advanced, minimally invasive procedure. SUBJECTS AND METHODS: Between 2004 and 2011, 240 consecutive patients underwent an LRP performed by a single surgeon and were divided into the first, second, and third groups of 80 patients each. Perioperative and oncologic outcomes were compared across the groups to assess the impact of the learning curve for LRP. All surgical complications were classified using the Clavien-Dindo system (CDS). RESULTS: Mean (range) patient age was 61 (43-78) years. The mean (range) level of prostate-specific antigen was 6.47 (3-18) ng/mL. The mean (range) Gleason sum was 6 (5-9). There was a significant reduction in the mean operative time (P<.001), mean anastomosis time (P<.001), mean blood loss (P<.001), mean hospital stay (P<.001), and mean minor CDS complications (P<.01) among the three groups as the series progressed. The D'Amico tumor stage was an independent factor for positive surgical margin across the learning curve (P<.001). CONCLUSIONS: Our study demonstrated safety and low morbidity of the LRP technique since the beginning of a learning curve development, in which up to 80 cases were necessary to create a plateau to improve faster perioperative parameters, although, from the plateau created, it requires a very large number of surgeries for slightly better, additional overall benefits. In spite of its complexity and steep learning curve, new surgeons can be encouraged in the LRP technique with mentorship training without compromising overall outcomes, permitting the wide spread of an alternative minimally invasive procedure in low-volume centers.

RESUMO

PURPOSE: The aim of the present study was to analyze long-term follow up (18-108 months) of different techniques and routes for laparoscopic repair of uretero-pelvic junction obstruction comparing efficacy and results. MATERIALS AND METHODS: A retrospective analyses of 133 laparoscopic pyeloplasties in 132 patients (mean age 35 years) between August 1995 and November 2008 was performed. Transperitoneal route was performed in 114 patients, and retroperitoneal route was performed in 19 patients. Different repair techniques (dismembered and non-dismembered) were applied at the surgeon's discretion. RESULTS: Average operative time was 127 minutes (range 45-370). Average blood loss was 127 mL, and mean hospital stay was 24 hours. Complications occurred in 9.6% of surgeries, and conversion rate was 1.7%. Urinary leak occurred after eight (6.1%) surgeries, all managed conservatively. Overall success rate of laparoscopic repair was 96%, higher for dismembered versus non-dismembered procedures (97% versus 89%, P = .04). CONCLUSION: Laparoscopic pyeloplasty is a reproducible, highly effective, and minimally invasive treatment for uretero-pelvic junction obstruction. Surgical technique affects operative time and long-term success rates. Dismembered techniques seem to remain more effective after a long-term follow up. Surgical route does not seem to affect success rates.

RESUMO

Laparoscopic partial nephrectomy (LPN) has emerged as a viable alternative for the conventional open nephron-sparing surgery (NSS). So far, an adequate renal parenchymal cutting and hemostasis, as well as caliceal repair remains technically challenging. Numerous investigators have developed techniques using different energy sources to simplify the technically demanding LPN. Herein we review these energy sources, discussing perceived advantages and disadvantages of each technique.

RESUMO

OBJECTIVE: Compare detrusor muscle of normal and patients with infravesical obstruction, quantifying the collagen and elastic system fibers. MATERIALS AND METHODS: We studied samples taken from bladders of 10 patients whose ages ranged from 45 to 75 years (mean = 60 years), who underwent transvesical prostatectomy for treatment of BPH. Control material was composed of 10 vesical specimens, removed during autopsies performed in cadavers of accident victims, with ages between 18 and 35 years (mean = 26 years). RESULTS: The results of collagen and elastic fibers quantification (volumetric density) demonstrated the following results in percentage (mean +/- standard deviation): collagen in BPH patients = 4.89 +/- 2.64 and 2.32 +/- 1.25 in controls (p < 0.0001), elastin in BPH patients = 10.63% +/- 2.00 and 8.94% +/- 1.19 in controls (p < 0.0001). CONCLUSION: We found that the components of connective tissue, collagen and elastic system fibers are increased in the detrusor muscle of patients with infravesical obstruction, when compared to controls.
