Summary
Urinomas occur in about 15% of boys with posterior urethral valves. These urine collections do not impact kidney function and asymptomatic cases require no specific treatment.
Area of Science:
- Pediatric Urology
- Nephrology
- Medical Imaging
Background:
- Posterior urethral valves (PUV) are a common congenital anomaly in male infants.
- Urinomas, collections of urine, can be a complication of PUV.
- Understanding urinoma incidence and impact is crucial for patient management.
Purpose of the Study:
- To determine the incidence and clinical significance of urinomas in boys with posterior urethral valves (PUV).
- To assess the impact of urinomas on renal function.
- To evaluate treatment strategies for urinomas in this population.
Main Methods:
- Retrospective review of 196 patients with PUV treated between 1953 and 2003.
- Comparison of patients with and without urinoma.
- Analysis of clinical data, including serum creatinine and renal function tests.
Main Results:
- Urinoma incidence was 9%, rising to 15% with routine ultrasonography.
- Perirenal urine collection, urinary ascites, and urinothorax were observed.
- Renal function and risk of end-stage renal failure were similar in patients with and without urinomas.
Conclusions:
- The actual incidence of urinomas in PUV patients is likely around 15%.
- Urinomas do not appear to negatively affect long-term renal function in PUV patients.
- Asymptomatic urinomas in PUV patients may not require specific intervention.

01:26Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
01:19Anatomy of the Genitourinary System II: Bladder and Urethra
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...
01:28Urinary Tract Calculi I: Introduction
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...
01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:22Ureters
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
