A simple operation for the management of simple, i.e. intravesical, ureteroceles, which we have named 'ostioplasty', is presented. After unroofing the ureterocele, the retracted, gaping ureteric ostium is advanced and fixed medially to the center of the bladder trigone with three 5-0 polyglycolic acid sutures. The exposed intravesical ureter is covered with a new mucosal layer formed from the mobilized lateral edges of the unroofed ureterocele, sutured together over the ureter with 5-0 polyglycolic acid. Ostioplasty has been used in 5 patients so far with excellent anatomic and functional results. It is a simple and valuable surgical option to standard ureterovesical reimplantation after excision of a simple ureterocele, provided that the ureterocele is of moderate size and the bladder trigone retains good muscular support.

Follicular cystitis (FC) is a chronic form of cystitis with uncertain etiology, characterized by the presence of lymphoid follicles in the bladder mucosa as a result of chronic irritation. This can be caused by various factors such as prolonged catheterization, lithiasis, recurrent urinary tract infections or neoplastic bladder pathology. Although it is a rare pathology, it is mainly seen in women over 50 years of age and manifests with nonspecific urinary symptoms such as dysuria, pollakiuria, haematuria and suprapubic pain.

Background: Sacrocolpopexy has become a favored treatment of pelvic organ prolapse due to its durability and efficacy. Sacrocolpopexy has not been standardized and there is no categorization scheme to facilitate communication or research efforts for the procedure. A systematic review was conducted to facilitate construction of a classification system for sacrocolpopexy based on extent of vaginal dissection described in the medical literature.

Background And Purpose: Late toxicity is substantial after chemotherapy for anal cancer. This study aimed to investigate the relationship between radiation dose to lower urinary tract sub-structures and the risk of late urinary toxicities, in patients with anal cancer treated with chemoradiotherapy or radiotherapy.
Materials And Methods: From 2015 to 2021, 314 patients with localized anal cancer were included in a national prospective registration study.

A 12 yr old female spayed American Staffordshire terrier was referred for stranguria, pollakiuria, and concern for a mass in the trigone of the urinary bladder. A urinalysis and abdominal ultrasound were performed to further investigate the bladder mass. Nematode larvae were identified in the urine, termed microfilaruria, while a caudal abdominal mass was found on ultrasound impinging on the urethra.

Introduction: Morphological changes in the prostatic urethra and bladder cavity resulting from Aquablation treatment are still unknown. This study aims to assess the safety and efficacy of Aquablation within one-year post-surgery, focusing on both functional and endoscopic outcomes.
Methods: Prospective enrollment of patients undergoing Aquablation (10/2018-04/2023) included those with baseline International Prostate Symptom Score (IPSS) ≥ 10, prostate volume from 40 to 80 mL, and Qmax ≤ 12 mL/s.
