The authors report the case of a male neonate presenting with a heterogeneous cystic mass in the right renal area with no identifiable renal unit. The diagnosis of right perirenal extracapsular uro-haematoma secondary to posterior urethral valve was proposed on the basis of the antenatal clinical history. The late discovery at 39 weeks of amenorrhoea (pregnancy not followed) of a foetus with trabeculated bladder associated with left ureteropelvic dilatation, and a cystic mass occupying the right lumbar fossa was highly suggestive of right urinoma secondary an infravesical obstacle. In this case, vaginal delivery was probably responsible for intracystic bleeding of the urinoma. The postnatal morphological assessment including ultrasound, retrograde cystourethrography and MRI confirmed the presence of a posterior urethral valve complicated by right uro-haematoma displacing the right kidney and left ureteropelvic dilatation. This lesions corresponds to a collection of urine and blood in the right perirenal space due to caliceal or parenchymal perforation secondary to raised urinary tract pressure above an obstacle. Subcapsular or extracapsular perirenal urinoma, sometimes detected in neonates with posterior urethral valve, reflects protective decompression of the urinary tract (safety valve effect), as in our case. The neonatal diagnosis of a heterogeneous renal cystic mass is sometimes difficult (polycystic renal dysplasia, cystic lymphangioma, cystic neuroblastoma, adrenal haematoma). In some cases, the antenatal history may suggest the diagnosis of perirenal urohaematoma secondary to infravesical obstruction.

Urethrovaginal fistulas are rare complications often arising from urethrovaginal injuries commonly due to obstetrical trauma, urethral surgeries, pelvic fractures, or neoplastic treatments. Here, we present a unique case involving a 23-year-old female patient with a large urethrovaginal fistula and complete anterior vaginal wall sloughing following prolonged obstructed labor. Nine months post-cesarean, she reported urine leakage via the vagina upon catheter removal, which intensified in an erect posture.

Introduction: Posterior urethral valve (PUV) is a congenital condition marked by obstructing persistent urogenital membrane, leading to urinary tract infections, bladder dysfunction, and kidney damage. It affects males only, mostly suspected antenatally and confirmed in early infancy. It requires early diagnosis and intervention to prevent long-term complications.

Objective: Urinary continence after radical prostatectomy is a crucial aspect of patient quality of life. The aim of this study was to identify the factors influencing urinary continence after robot-assisted laparoscopic radical prostatectomy, focusing on the role of anterior reconstruction.
Methods: We collected clinical data from 375 patients at a single institution.

Introduction: Numerous anatomical theories have been developed to explain women stress urinary incontinence (SUI) and improve its management. The transperineal ultrasound is an efficient and non-invasive exam that perfectly studies the bladder neck movement and the urethral anatomy. The measurement of the static portion of the distal urethral length, considered as the functional urethral length (FUL), and of the posterior urethral closure angle (PUCA) have not been studied before and could be of interest.

Introduction: Posterior Urethral Valves (PUV) are rare congenital anomalies of the male urinary tract that can lead to urethral obstruction and increased risk of kidney disease. Traditional diagnosis relies on subjective interpretation of imaging techniques. This study aimed to automate and increase accuracy of PUV detection in voiding cystourethrography (VCUG) images using an AI-based pipeline.
