Summary
A patient developed a ureteric injury and urinoma after rectal cancer surgery. Prompt diagnosis and emergent ureteric reimplantation were crucial for successful management of this surgical complication.
Area of Science:
- Urology
- Surgical Oncology
- Gastroenterology
Background:
- Laparoscopic low anterior resection is a standard procedure for rectal adenocarcinoma.
- Postoperative complications can arise, necessitating prompt diagnosis and management.
- Ureteric injury is a rare but serious complication following pelvic surgery.
Purpose of the Study:
- To report a case of iatrogenic ureteric injury and urinoma following laparoscopic low anterior resection.
- To highlight the diagnostic challenges and successful management of this complication.
Main Methods:
- A 70-year-old male patient underwent laparoscopic low anterior resection for rectal adenocarcinoma.
- Postoperative high drain output and elevated drain creatinine levels prompted further investigation.
- Computed tomography (CT) scan confirmed left ureteric injury and urinoma.
Main Results:
- The patient presented with significant drain output (800 mL) and markedly elevated drain creatinine (300 mmol/L) compared to serum creatinine (100 mmol/L).
- CT imaging revealed a left ureteric injury with a resultant urinoma.
- Emergent ureteric reimplantation was successfully performed after urology consultation.
Conclusions:
- Iatrogenic ureteric injury can occur during laparoscopic low anterior resection for rectal cancer.
- High drain output and elevated drain creatinine are critical indicators of potential urinary tract injury.
- Early recognition and prompt surgical intervention, such as ureteric reimplantation, are essential for favorable outcomes.

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...

01:29Acute Kidney Injury II: Pathophysiology
28
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...

01:26Urinary Tract Infection I: Introduction
24
Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

01:27Acute Pyelonephritis I: Introduction
21
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...

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...
