An animal study was undertaken to develop a balloon dilation technique that could be used in humans to treat the common ailment of benign prostatic hypertrophy. Dogs were used as a model because of the similarities in the prostate between the two species and the ready availability of the canines. A retrograde transurethral approach was used for dilation. Balloon catheters, 8-20 mm in diameter, were used. Significant, long-lasting dilatation of the prostatic urethra was not accomplished until 20-mm balloons (or two 10-mm ones) inflated for 10 minutes were used. The animals were followed for up to 14 months. No deleterious histologic effects of dilation were identified within the urethra or prostate that could lead to stenosis of the prostatic urethra in later stages.

Introduction: Transient stress urinary incontinence (SUI) after holmium laser enucleation of prostate (HoLEP) is commonly linked to intraoperative injury of the external urethral sphincter (EUS). We assessed the reliability of the post-HoLEP endoscopic appearance of the membranous urethra mucosa (MUM) in predicting post-HoLEP continence.
Methods: Forty HoLEPs were prospectively recorded by an artificial intelligence video platform capable of segmenting clips by surgical steps.

Objective: This study aimed to evaluate outcomes and complications in dogs with urothelial carcinoma (UC) of the bladder trigone treated with total cystectomy using uretero-prepuce/vagina/cutaneous anastomosis combined with medical treatment.
Animals: Twenty-one dogs.
Procedure: Total cystectomy was completed as follows: The whole bladder and urethra were removed, and the ureters were anastomosed to the skin in 1 case and to the vagina in 9 cases in females.

Prostate ductal adenocarcinoma (PDA) is an aggressive subtype of prostate adenocarcinoma (PA). It can be found either in the peripheral zone, typically associated with acinar PA, or centrally in or around the verumontanum as a urethral polyp. Whether centrally occurring PDAs are biologically and genetically different compared to peripheral PDA remains unknown.

Minimally invasive methods were sought for faster recovery from benign prostatic hyperplasia (BPH) and lower urinary tract (LUTS) symptoms. For this, the search for effective, low-side-effect methods for tissue ablation, particularly for managing BPH and certain bladder pathologies, has been continued to advance. In this regard, the energy released during the formation of hydrodynamic cavitation bubbles offers an alternative treatment method.
