Aim Of The Study: We present the experimental results of a new technique that makes use of the anal sphincter to achieve urinary continence in individuals with major congenital defects of the urinary sphincter.
Methods: 50 New Zealand White rabbits were assigned to one of 6 groups and a different surgical procedure was carried out for each group under general anaesthesia with isoflurane alone or isoflurane and local anaesthesia. Variables of interest were: number, consistency and morphology of the faeces, number, shape and location of the stains of urine, histological changes and biochemical parameters in blood.
Results And Conclusions: The best anaesthetic levels were obtained with 2 % isoflurane and local anaesthesia. The surgical procedure demonstrated its usefulness in achieving urinary continence in all rabbits, although an initial self-limited period of incontinence was common. No histologic alterations were detected, but a significant increase in the levels of urea and creatinine in blood was identified, most likely reflecting an obstructive uropathy.

The artificial urinary sphincter has been an effective treatment for stress urinary incontinence caused by intrinsic sphincter deficiency in women. However, the use of this device has been limited by the technical difficulties and risks associated with the open implantation procedure. Preliminary studies using robotic techniques have shown promising results, but only one small study has compared robotic to open procedures.

: Radical cystectomy (RC) is the standard treatment for muscle-invasive and high-risk non-muscle-invasive bladder cancer, but it often results in significant functional impairments, including sexual and urinary dysfunction, adversely affecting quality of life (QoL). Sexual-sparing robotic-assisted radical cystectomy (RARC) has been introduced to mitigate these effects. This review evaluates the oncological and functional outcomes of sexual-sparing RARC in male and female patients.

: Robot-assisted radical prostatectomy (RARP) for the treatment of prostate cancer (PCa) has been standardized over the last 20 years. At our institution, only n = 3 rob arms are used for RARP. In addition, n = 2, 12 mm lap trocars are placed for the bedside assistant symmetrically at the midclavicular lines, which allows for direct pelvic triangulation and greater involvement of the assisting surgeon.

Background: To propose the bladder mucosal smoothness (BMS) grade and validate a predictive model including MRI parameters preoperatively that can evaluate the early recovery of urinary continence (UC) after laparoscopic radical prostatectomy (LRP).
Methods: A retrospective analysis was conducted on 203 patients (83 patients experienced UI at the three-month follow-up) who underwent LRP in our medical center and were diagnosed with prostate cancer (PCa) from June 2016 to March 2020. Patients' clinicopathological data were collected.
