Retroperitoneal Robotic-Assisted Laparoscopic Pyeloplasty: A 10 Year Experience in a Single Institution.

Pelvi-ureteric junction (PUJ) obstruction was traditionally treated with open pyeloplasty. In recent decades, the development of minimally invasive techniques, including laparoscopic and later robotic surgery, has transformed treatment. The transperitoneal approach has most commonly been undertaken, with a few institutions reporting outcomes of the retroperitoneal approach.

Warm ischemia time length during on-clamp partial nephrectomy: does it really matter?

Background: The impact of warm ischemia time (WIT) on renal functional recovery remains controversial. We examined the length of WIT>30 min on the long-term renal function following on-clamp partial nephrectomy (PN).

Methods: Data from 23 centers for patients undergoing on-clamp PN between 2000 and 2018 were analyzed.

Experiences of a "COVID protected" robotic surgical centre for colorectal and urological cancer in the COVID-19 pandemic.

The recent COVID-19 pandemic led to the cancellation of elective surgery across the United Kingdom. Re-establishing elective surgery in a manner that ensures patient and staff safety has been a priority. We report our experience and patient outcomes from setting up a "COVID protected" robotic unit for colorectal and renal surgery that housed both the da Vinci Si (Intuitive, Sunnyvale, CA, USA) and the Versius (CMR Surgical, Cambridge, UK) robotic systems.

Nephrometry scores: a validation of three systems for peri-operative outcomes in retroperitoneal robot-assisted partial nephrectomy.

Objective: To externally validate the RENAL, PADUA and SPARE nephrometry scoring systems for use in retroperitoneal robot-assisted partial nephrectomy (RAPN).

Materials And Methods: Nephrometry scores were calculated for 322 consecutive patients receiving retroperitoneal RAPN at a tertiary referral centre from 2017. Patients with multiple tumours were excluded.

A Simple Clinical Tool for Stratifying Risk of Clinically Significant CKD after Nephrectomy: Development and Multinational Validation.

Background: Clinically significant CKD following surgery for kidney cancer is associated with increased morbidity and mortality, but identifying patients at increased CKD risk remains difficult. Simple methods to stratify risk of clinically significant CKD after nephrectomy are needed.

Methods: To develop a tool for stratifying patients' risk of CKD arising after surgery for kidney cancer, we tested models in a population-based cohort of 699 patients with kidney cancer in Queensland, Australia (2012-2013).

Asynchronous bilateral leiomyomata of tunica vaginalis: A case report.

Leiomyomata are smooth muscle tumours that are slow growing and benign. We report a case of bilateral leiomyomata arising from tunica vaginalis. A 65 year old presented with a 5-year history of a slow growing left testicular mass and underwent radical orchidectomy.

Retroperitoneal Robot-Assisted Partial Nephrectomy in Obese Patients.

To report our experience with retroperitoneal robotic-assisted partial nephrectomy (RAPN) in obese patients. From April 2012 to December 2018, 127 patients with body mass index (BMI) ≥30 kg/m underwent RAPN, of whom 110 patients had retroperitoneal RAPN. We reviewed the patients' demographic, operative data, perioperative and postoperative complications, and postoperative histology.

Analysis of Factors' Association with Risk of Postoperative Urosepsis in Patients Undergoing Ureteroscopy for Treatment of Stone Disease.

Introduction: To investigate which patient, stone, infective, and surgical factors were most likely to increase the risk of postoperative urosepsis within 28 days of ureteroscopy (URS) and laser stone fragmentation for ureteral or renal stones.

Methods: Data were collected prospectively in a single National Health Service institution. A logistic regression model was used to assess the association of factors with postoperative urosepsis.

What is the feasibility of switching to 200IU OnabotulinumtoxinA in patients with detrusor overactivity who have previously received 300IU?

Introduction: To assess the feasibility of converting from 300IU to 200IU OnabotulinumtoxinA in patients diagnosed with either idiopathic detrusor overactivity (IDO) or neurogenic detrusor overactivity (NDO).

Material And Methods: Retrospective case-notes review of patients who were converted from 300IU to 200IU OnabotulinumtoxinA. Subjective patient reported improvements at interview and bladder diary reported parameters of urgency, urgency incontinence, frequency and nocturia.

Conservative management of pelvi-ureteric junction obstruction (PUJO): is it appropriate and if so what duration of follow-up is needed?

Objective: • To establish whether it is safe to manage minimally symptomatic and asymptomatic pelvi-ureteric junction obstruction (PUJO) conservatively.

Patients And Methods: • In all, 50 patients with PUJO diagnosed with dynamic renography, and monitored with at least two renograms.

Results: • In all, 19 patients were totally asymptomatic, while 31 patients had minimal symptoms at time of diagnosis.

Transurethral resection biopsy as part of a saturation biopsy protocol: a cohort study and review of the literature.

Objective: To evaluate the prostate cancer (CaP) detection rate and morbidity of performing a transurethral resection biopsy of the prostate (TURBP) at the same time as a saturation biopsy (SBx).

Patients: A total of 102 men with previous negative transrectal ultrasound (TRUS) biopsies underwent a SBx under formal anaesthesia. Fifty-four [54 (52.
