Robotic Radical Cystectomy with Intracorporeal Urinary Diversion - Tips and Tricks.

Radical cystectomy represents the standard surgical treatment in case of muscle invasive bladder cancer. During the last two decades a change in the surgical approach of the MIBC has been observed, from open surgery to minimal invasive surgery. Nowadays, in the majority of tertiary urologic centers, robotic radical cystectomy with intracorporeal urinary diversion represents the standard surgical approach. The aim of the current study is to describe in detail the surgical steps of the robotic radical cystectomy and the reconstruction of the urinary diversion and to present our experience. From the surgical point of view, the most important principles which should guide the surgeon when performing this procedure are: 1. Good working place and access both to the pelvis and abdomen and use of the "technique of spaces" 2. Respect the oncological principles of the surgery with attention to the margin resection and limitation of the risk of tumour spillage; 3. Attention to both the ureter and bowel manipulation in order to avoid grasping lesions; 4. High care in realisation of the uretero-ileal anastomosis so that good long term functional results are achieved. We analyzed our database of 213 patients diagnosed with muscle invasive bladder cancer who underwent minimally invasive radical cystectomy (laparoscopic and robotic approaches) between January 2010 and December 2022. We identified 25 patients for whom the robotic approach was used to perform the surgery. Despite being one of the most challenging urologic surgical procedures, with careful preparation and training, the surgeon is able to achieve the maximum oncological and functional results by performing robotic radical cystectomy with intracorporeal urinary.

Analyzing the learning curves of a novice and an experienced urologist for transrectal magnetic resonance imaging-ultrasound fusion prostate biopsy.

BACKGROUND: The aim of the current study was to evaluate and compare the learning curves of transrectal magnetic resonance imaging-ultrasound fusion biopsy for two urologists with different backgrounds (Operator 1: experienced, self-trained and Operator 2: novice, trained by a mentor/MRI reading courses). METHODS: A cohort of 400 patients who underwent fusion prostate biopsy in our department was analyzed. The learning curves were assessed in terms of overall and clinically significant prostate cancer (PCa) detection rates, percentage of positive biopsy cores/targeted and the percentage of PCa tissue on positive targeted cores. RESULTS: Increasing trends were observed for both urologists in terms of all biopsy outcomes during the study time. For the novice urologist, a significant increase was observed for overall PCa detection rate, but not for clinically significant disease (25.44%, P=0.04/15%, P=0.145). Operator 1 showed an increasing diagnosis yield of clinically significant disease up to 104 cases. Similar cancer detection rates were observed when comparing the first and last biopsies performed by both operators. Multivariate analysis adjusted for age, PSA, prostate volume, lesion diameter and PIRADS score showed an increase of PCa detection with 51% for every 52 biopsies performed (P=0.022). CONCLUSIONS: When starting with magnetic resonance imaging-ultrasound fusion prostate biopsy, mentoring and prostate magnetic resonance imaging reading training allow a novice urologist to demonstrate a good initial PCa detection rate. After about 52 cases, he reached a stable PCa and clinically significant PCa detection rate, that was similar to that of an experienced urologist.
