Robot-Assisted Radical Prostatectomy by Lateral Approach: Technique, Reproducibility and Outcomes.

BACKGROUND: Radical prostatectomy by lateral approach allows performing a prostatectomy through a buttonhole, with direct access to the seminal vesicle and fully sparing the anterior pubovesical complex. Our aim is to show the results of reproducing the technique of robotic radical prostatectomy by lateral approach, in terms of intraoperative, postoperative, oncological and functional parameters. METHODS: We analyzed 513 patients submitted to robotic radical prostatectomy by lateral approach from January 2015 to March 2021, operated on by two surgeons in our institution. The oncological and functional results of both surgeons were compared. RESULTS: When comparing both surgeons, the rate of positive surgical margins (PSM) was 32.87% and 37.9% and significant surgical margins (PSM > 2 mm) were 5.88% and 7.58% (p = 0.672) for surgeon 1 and surgeon 2, respectively. Immediate continence was 86% and 85% and sexual potency at one year 73% and 72%, with a similar rate of complications for surgeon 1 and 2. CONCLUSIONS: Radical prostatectomy by the lateral approach technique with preservation of the anterior pubovesical complex is reproducible and offers good oncological and functional results.

Prostate Mapping for Cancer Diagnosis: The Madrid Protocol. Transperineal Prostate Biopsies Using Multiparametric Magnetic Resonance Imaging Fusion and Micro-Ultrasound Guided Biopsies.

PURPOSE: We assessed the prostate cancer detection accuracy of transperineal prostate biopsy using multiparametric magnetic resonance imaging/ultrasound fusion targeted biopsy and micro-ultrasound during the same procedure. Micro-ultrasound is a new high-resolution imaging system that allows real-time targeted biopsy. MATERIALS AND METHODS: A total of 194 consecutive patients underwent transperineal prostate biopsies using real-time targeted micro-ultrasound (ExactVu™) and ultrasound fusion targeted biopsy (BiopSee®) in the same procedure, from February 2018 to September 2019. Biopsies were performed using a transperineal needle guide attached to the 29 MHz high-resolution micro-ultrasound transducer. RESULTS: The overall positive rate was 56% (108) for prostate cancer and 42% (81) for clinically significant prostate cancer (Gleason Grade Group greater than 1), and adding micro-ultrasound and magnetic resonance imaging detected significantly more clinically significant prostate cancer than systematic biopsy (p <0.001). Micro-ultrasound found 12 of 108 (11%) prostate cancers that were missed by all other techniques and 11 (92%) were clinically significant prostate cancer. PI-RADS® and PRI-MUS™ (Prostate Risk Identification Using Micro-Ultrasound) were strong predictors of clinically significant prostate cancer in a logistic regression model (AUC 0.76). For prostate specific antigen greater than 4 ng/ml, PI-RADS greater than 3, there was an improvement in detection rate between PRI-MUS 4 and PRI-MUS 5 (52% Gleason Grade Group greater than 1 to 92% Gleason Grade Group greater than 1). No fever or clinical infection was observed and 17 (8.7%) patients presented with minor complications (Clavien Dindo I). CONCLUSIONS: This is the first study using a transperineal approach for micro-ultrasound guided biopsy and multiparametric magnetic resonance imaging fusion biopsy. The results show a high accuracy for prostate cancer and clinically significant prostate cancer diagnosis, without infectious complications. The proposed method should be validated in large randomized clinical trials.

Protocolo de actuación de enfermería quirúrgica en cirugía robótica / Surgical nursing intervention protocol in robotic surgery

La aparición de la tecnología robótica ha conllevado la actualización del personal de enfermería tomando un papel fundamental aquellos encargados de la preparación y puesta en marcha del sistema, del instrumental y de la atención de detalles durante el desarrollo de la misma. Describimos el protocolo de actuación de enfermería en cirugía robótica en nuestro hospital. El equipo de cirugía robótica desde la implantación del sistema ha ejercido una actividad asistencial y docente con los profesionales de nueva incorporación. Es importante contar con un personal cualificado y especializado que proporcione un cuidado eficaz de manera eficiente y seguro para el paciente, sin olvidar mantener actualizados los conocimientos e iniciativas que se producen en el campo de la enfermería y la robótica

The appearance of robotic technology has led update nursing professionals, playing a key role those nurse team is responsible for instrumental and robotic system, taking care on all details during surgery. We describe a surgical nursing intervention protocol in robotic surgery in our institution. Since robotic protocol system implementation, robotic surgery team has performed assistant work and training activity of new team or visiting members. Qualified and specialized team is key in order to provide an effective, efficient and safety healthcare to patients. Keep update knowledge in nursing and robotic field is fundamental
