Summary
A loosened acetabular reinforcement cage caused bladder perforation and recurrent hematuria. Revision surgery successfully removed the infected hip prosthesis, resolving symptoms.
Area of Science:
- Orthopedic surgery
- Urology
- Biomaterials science
Background:
- Acetabular bone defects often require reinforcement cages for reconstruction.
- Burch-Schneider reinforcement rings are utilized in complex acetabular reconstructions.
- Complications associated with orthopedic implants require careful monitoring and management.
Observation:
- A case of a loosened Burch-Schneider reinforcement ring leading to urinary bladder perforation.
- Recurrent macrohaematuria was the primary presenting symptom.
- Diagnostic procedures confirmed the bladder perforation secondary to the loosened implant.
Findings:
- Interdisciplinary revision surgery was performed for the acetabular defect and prosthesis.
- Severe acetabular bone destruction and hip prosthesis infection were identified.
- The infected total hip prosthesis was explanted during revision surgery.
Implications:
- This case highlights a rare but serious complication of acetabular reinforcement cages.
- Prompt diagnosis and multidisciplinary intervention are crucial for managing such complications.
- Successful management can lead to resolution of symptoms and improved patient mobility.

01:22Esophageal Perforation-I: Introduction
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

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...

01:25Urinary Tract Calculi VI: Surgical Management
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
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...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
