ABSTRACT Introduction: Salvage Radical Prostatectomy after radiation therapy is challenging and associated with high rates of serious complications (1, 2). The novel Retzius-Sparing RARP (RS-RARP) approach has shown excellent continence outcomes (3, 4). Purpose: To describe step-by-step our Salvage Retzius-Sparing RARP (sRS-RARP) operative technique and report feasibility, safety and the preliminary oncological and continence outcomes in the post-radiation scenario. Materials and Methods: Twelve males presenting local prostate cancer recurrence after radiotherapy that underwent sRS-RARP were included. All patients performed preoperative multiparametric MRI and PSMA-PET. Surgical technique: 7cm peritoneum opening at Douglas pouch, Recto-prostatic space development, Seminal vesicles and vas deferens isolation and section, Extra-fascial dissection through peri-prostatic fat, Neurovascular bundle control, Bladder neck total preservation and opening, Anterior dissection at Santorini plexus plane, Apex dissection with urethra preservation and section, Prostate release, Vesicouretral modified Van Velthoveen anastomosis, Rocco Stitch, Oncological and continence outcomes reported with minimum 1-year follow-up. Results: Ten patients had previously received external beam radiation (EBR) whereas two received previous brachytherapy plus EBR. At 1, 3 and 12 months after surgery, 25%, 75% and 91.6% of the men used one safety pad or less, respectively. No major complications or blood transfusions were reported. Final pathology reported pT2b 41.6%, pT2c 33.3% and pT3a 25%, positive surgical margins 25%, positive lymph nodes were not found, biochemical recurrence 16.6%. Conclusion: Salvage Retzius-Sparing Robotic Assisted Radical Prostatectomy approach appears to be technically feasible and oncologically safe with potential to provide better continence outcomes.

BACKGROUND AND OBJECTIVES: Ureteral Reimplant is commonly used in pediatric and gyne-cologic surgery. Most techniques demand an experienced surgeon and lasts 2-3 hours. There is no consensus about the preferred technique until today. We report a simple modification of the Taguchi to reduce duration and make it more suitable for laparoscopic approach. METHOD: Three patients underwent distal ureteral reimplant, based on our modified Taguchi minimally invasive approach technique. Cystography and ultrasonography were performed on the 30th, 90th and 180th postoperative days to monitor kidneys; a one-year follow-up for recurrence or clinical symptoms was also performed. RESULTS: Operative time for ureteral reimplant using our technique was 15-25 minutes. The results of the performed exams on postoperative days showed normal kidneys without hydro-nephrosis. At the one-year follow-up no signs of recurrence or clinical symptoms were present. CONCLUSION: Our modifications allowed a faster and easier management of distal ureteral reimplant, with excellent perioperative and post-operative outcomes. To our knowledge this is the first detailed description of this technique through minimally invasive approach. However, further studies and a longer follow up will be necessaries to confirm the long-term outcomes and clinical benefits of our technical proposal.

JUSTIFICATIVA E OBJETIVOS: O reimplante ureteral é comumente utilizado em cirurgia pediátrica e ginecológica. A maioria das técnicas exigem um cirurgião experiente e dura 2-3 horas. Não há consenso sobre a técnica preferida até hoje. Relatamos uma modificação simples do Taguchi para reduzir sua duração e torná-lo mais adequado para a abordagem laparoscópica. MÉTODO: Três pacientes foram submetidos a reimplante ureteral distal, com base na técnica de abordagem minimamente invasiva de Taguchi modificada. Cistografia e ultra-sonografia foram realizadas no 30º, 90º e 180º dias de pós-operatório para monitorização dos rins; um acompanhamento de um ano para recorrência ou sintomas clínicos também foi realizado. RESULTADOS: O tempo operatório para o reimplante ureteral utilizando a nossa técnica foi de 15-25 minutos. Os resultados dos exames realizados nos dias pós-operatórios mostraram rins normais sem hidronefrose. No seguimento de um ano não houve sinais de recorrência ou sintomas clínicos. CONCLUSÃO: Nossas modificações permitiram um manejo mais rápido e fácil do reimplante ureteral distal, com excelentes resultados peri- e pós-operatórios. Tanto quanto sabemos, esta é a primeira descrição detalhada desta técnica através de abordagem minimamente invasiva. No entanto, estudos adicionais e um acompanhamento mais longo serão necessários para confirmar os resultados a longo prazo e os benefícios clínicos da técnica proposta.

ABSTRACT 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.
