Introduction: We describe a method of robotic ureterocalicostomy (RALUC) with the Da Vinci Single Port (SP) platform and present clinical outcomes in our cohort of patients.

Materials And Methods: We retrospectively reviewed all patients undergoing RALUC with the SP platform in a single-institution, IRB-approved database between 2020-2023. Demographics, preoperative, intraoperative, and postoperative outcomes were collated.

Purpose Of Review: The present study reviews contemporary literature focused on transplantation and tissue substitutes for the purposes of masculinizing genital gender affirming surgery. Additional background is provided for both topics to provide a more comprehensive understanding of the modern applications.

Recent Findings: Genitourinary vascularized composite allotransplantation has become a reality in recent years with several cases reported worldwide in cisgender men with promising reports of urinary and sexual function.

Introduction: We evaluate the rate of developing ciprofloxacin resistance in patients undergoing repeat prostate biopsies (PBx), associated risk factors, and impact on complications.

Materials And Methods: We retrospectively evaluated pre-procedural rectal culture (RCx) data in men undergoing PBx from 1/1/2016 to 1/15/2021. Univariate and multivariate logistic regression were utilized to identify risk factors associated with development of antibiotic resistance.

Objective: To assess urologists' attitudes toward treating lesbian, gay, bisexual, transgender, or queer (LGBT) patients and counseling practices during diagnosis and treatment of prostate cancer.

Methods: A 35-question survey was sent to program directors of U.S.

With the widespread dissemination of robotic surgical platforms, pathologies that were previously deemed challenging can now be treated more reliably with minimally invasive procedures via the robot. The advantages of precise articulation for dissection and suturing, tremor reduction, three-dimensional magnified visualization, and small incisions allow for the management of diverse lower urinary tract (LUT) disease. These may include recurrent or refractory bladder neck stenoses or intracorporeal urinary diversion with excellent perioperative and functional outcomes.

Objective: To provide a summary of surgical technique and outcomes for Heineke-Mikulicz preputioplasty (HMP), a foreskin-preserving surgical treatment for phimosis in the adult population.

Methods: We retrospectively reviewed 7 patients who underwent HMP by a single surgeon from May 2017 to May 2021. Variables included patient demographics, intraoperative considerations, and post-operative course.

Objective: To describe a novel method of robotic assisted laparoscopic parastomal hernia repair (RAL-PHR), including the evolving use of the Da Vinci Single Port (SP) robotic system.

Methods: Demographic, intraoperative, and postoperative variables were collected for patients who underwent RAL-PHR. The technique for RAL-PHR utilizes a 3 cm incision in the contralateral upper quadrant for the robotic trocar and a 12 mm assistant port.

Purpose Of Review: Describe the ACGME's changes to the PGY-1 year in urology and discuss the benefits and challenges faced by training programs.

Recent Findings: There are no publications detailing the integration of the PGY-1 year in urology; however, response of other surgical subspecialties to their own integration has been studied. Benefits of integration include earlier exposure to techniques and knowledge specific to urology, potentially leading to increased preparedness for next steps in training and exams.

Objective: To provide insights into the long-term impact of radical retro-pubic prostatectomy (ORRP) on lower urinary tract symptoms (LUTS) which are age and prostate dependent and adversely impact quality of life.

Methods: 1995 men undergoing ORRP enrolled in a prospective longitudinal outcomes study. The American Urological Association Symptom Index was self-administered before ORRP and at predetermined time-points after surgery.

Purpose: We examined the time dependent rates of urinary continence following open retropubic radical prostatectomy.

Materials And Methods: A total of 1,995 men treated with radical prostatectomy were enrolled in a prospective longitudinal outcomes study. The UCLA-PCI-UFS (UCLA-Prostate Cancer Index-Urinary Function Index) was administered at baseline, and 3, 6, 12, 24, 96, 120 and 180 months after open retropubic radical prostatectomy.
