Summary
Proliferative cystitis can cause hydronephrosis, a rare condition. Transurethral resection of the bladder tumor (TURBT) is effective, though some cases require further intervention like ureteralileostomy.
Area of Science:
- Urology
- Pathology
Background:
- Proliferative cystitis is a rare condition.
- It can lead to significant urinary tract issues like hydronephrosis.
Observation:
- Three patients presented with symptoms including painful urination, gross hematuria, and urinary frequency.
- Cystoscopy revealed papillary sessile tumors from the bladder neck to the orifice.
Findings:
- Transurethral resection of the bladder tumor (TURBT) was performed due to lack of response to medical treatment.
- Pathological diagnosis confirmed cystitis glandularis (intestinal or typical type) without malignancy.
- Hydronephrosis resolved in two patients post-TURBT; one required ureteralileostomy.
- No tumor recurrence was observed five years after treatment.
Implications:
- This case series highlights the importance of recognizing and managing proliferative cystitis.
- Surgical intervention, such as TURBT, is a viable treatment option.
- Further management may be necessary for persistent hydronephrosis.

Acute Pyelonephritis I: Introduction
1.5K
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...

Disorders of the Urinary System
2.1K
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

Urinary Tract Infection II: Pathophysiology
1.4K
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

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...

Nephrons
8.1K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Acute Kidney Injury II: Pathophysiology
2.2K
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...
