Summary
Subcapsular renal hematoma (SRH) after ureterolithotripsy is rare, occurring in 0.52% of cases. Severe hydronephrosis and narrow ureters are key risk factors, with most cases resolving conservatively.
Area of Science:
- Urology
- Nephrology
- Medical Imaging
Background:
- Subcapsular renal hematoma (SRH) is a potential complication following ureterolithotripsy (URL).
- Understanding its incidence, risk factors, and outcomes is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of SRH after URL.
- To identify associated risk factors, clinical features, and treatment outcomes.
Main Methods:
- Retrospective review of 2098 patients undergoing URL between 2014 and 2023.
- Analysis of clinical data including patient demographics, stone indicators, and perioperative information.
- Statistical analysis using Student's t-test and Chi-square/Fisher's exact test.
Main Results:
- SRH incidence was 0.52% (11 cases), confirmed by non-contrast CT.
- Risk factors included severe hydronephrosis (54.55%) and narrow ureters (45.45%).
- SRH patients had significantly longer hospital stays (11.64 days vs 3.87 days).
Conclusions:
- SRH following URL is uncommon, with severe hydronephrosis and narrow ureters as significant risk factors.
- Conservative management is effective for most cases, though prolonged hospitalization may occur.
- Complete resolution was observed in all cases within a 4-month follow-up period.

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.
