Summary
Reflex anuria (RA) is a rare condition causing sudden urine output reduction due to stimuli affecting the urinary tract. Prompt identification and stenting are crucial for managing RA, especially post-surgery.
Area of Science:
- Urology
- Surgical Oncology
Background:
- Reflex anuria (RA) is a rare complication characterized by a sudden decrease in urine output.
- It stems from reflex ureteral or renal arteriole spasm following trauma or irritation to the urinary tract.
Observation:
- RA is documented after colorectal and gynecological surgeries, often necessitating ureteric stenting.
- It can also occur post-HIPEC for colorectal cancer, leading to ureteral inflammation, hematuria, clots, and obstruction.
Findings:
- Inflammation from HIPEC can cause both RA and post-renal obstruction due to clot formation.
- Maintaining high postoperative urine output is vital to prevent clots and obstruction.
Implications:
- Early identification and treatment of RA, including ureteric stenting, are essential, even without visible hydronephrosis.
- This proactive approach can prevent complications like post-renal obstruction following specific surgical procedures.

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
