|August 4, 2001
Summary
The Mainz pouch II procedure offers a continent urinary diversion option after cystectomy for bladder tumors. This technique is well-tolerated with manageable complications, making it a recommended surgical choice.
Area of Science:
- Urology
- Surgical Oncology
Context:
- Renewed interest in ureterosigmoidostomy for continent urinary diversion.
- Advancements in surgical techniques and materials facilitate improved outcomes.
- The Mainz pouch (Sigmarectum pouch) is a modification of the classical ureterosigmoidostomy.
Purpose:
- To evaluate the outcomes of the Mainz pouch II procedure for continent urinary diversion.
- To assess the safety and efficacy of this technique in patients with urinary bladder tumors.
Summary:
- 46 "Mainz II" pouch operations were performed between 1992-1999 in patients with bladder tumors.
- The series included 41 men and 5 women aged 42-80 years.
- Postoperative complications included urinary fistulae (6.52%), local relapse (8.69%), and distant metastases (4.35%). Six patients (0.7%) had a fatal outcome.
Impact:
- The Mainz pouch II is a convenient, atraumatic, and well-tolerated continent urinary diversion method.
- Complications are infrequent and rarely require surgical intervention.
- This procedure is recommended following cystectomy for bladder cancer.

01:32Filtration and Urine Formation
The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.
01:24Physiology of Urine Formation
Urine formation is an essential function of the human body. It plays a critical role in maintaining homeostasis by regulating the volume and composition of body fluids. The kidneys, the primary organs involved in this process, filter blood to remove waste products and excess substances, ultimately producing urine.

01:20Formation of Dilute Urine
The formation of dilute urine is a critical renal adaptation that maintains fluid balance, particularly during periods of high fluid intake. This process primarily involves the juxtamedullary nephrons. By adjusting the permeability of water and ions in response to physiological conditions, the kidneys can either conserve or excrete water, resulting in concentrated or dilute urine.

01:23Formation of Concentrated Urine
There is a gradient of solutes in the interstitial fluid from the renal cortex through the medulla, known as the medullary osmotic gradient. The juxtamedullary nephrons establish and maintain this gradient using countercurrent mechanisms with loops extending deep into the medulla. These nephrons also use countercurrent mechanisms to regulate urine volume and concentration. The interaction between the descending and ascending limbs of the nephron loop creates an osmotic gradient through...
01:20Physiology of the Genitourinary System III: Urine Concentration and Dilution
The kidneys concentrate or dilute urine to maintain water and electrolyte balance. Nephrons, particularly the loop of Henle, play a crucial role in this process through the countercurrent multiplication system. This system establishes a high osmolarity in the renal medulla, which is essential for water reabsorption. In the loop of Henle’s descending limb, water is reabsorbed into the surrounding medulla due to its permeability to water. In contrast, the ascending limb actively transports...
01:29Urine Studies I: Urinalysis
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...
