This case study shows that transurethral resection of the prostate (TUR-P) effectively treats IgG4-related prostatitis. The procedure significantly improved urinary function in a patient with this rare condition.
Area of Science:
- Urology
- Immunology
- Pathology
Background:
- IgG4-related prostatitis is a rare condition presenting with lower urinary tract symptoms.
- It can be misdiagnosed as benign prostatic hyperplasia, delaying appropriate treatment.
Purpose of the Study:
- To report a successful treatment of IgG4-related prostatitis using transurethral resection of the prostate (TUR-P).
- To highlight the importance of recognizing IgG4-related prostatitis for effective patient management.
Main Methods:
- A case report of a 47-year-old male with a history of autoimmune pancreatitis and sclerosing cholangitis.
- Initial diagnosis of benign prostatic hyperplasia based on imaging and uroflowmetry.
- Treatment with TUR-P after medical management failed.
Main Results:
- Pathological examination confirmed dense lymphoplasmacytic inflammation with numerous IgG4-positive cells, diagnosing IgG4-related prostatitis.
- Postoperative urinary function dramatically improved.
- Good urinary function was maintained for 3 years without further intervention.
Conclusions:
- Transurethral resection of the prostate (TUR-P) is an effective treatment for IgG4-related prostatitis.
- Accurate diagnosis and understanding the impact of IgG4-related prostatitis on urinary function are crucial for successful treatment.
