Transurethral resection of an uncommon Brunn's cyst: A resolution for lower urinary tract symptoms

Abstract

Objective: To present the first surgical video of a patient with Brunn's cyst accompanied by lower urinary tract symptoms (LUTS) who underwent transurethral deroofing and resection. Patients and Surgical procedure: A 44-year-old male patient with LUTS of frequency and urgency was evaluated with cystoscopy and ultrasonography, which revealed a cystic lesion located at the bladder neck. The LUTS were evaluated using the self-administered international prostate symptom score questionnaire and uroflowmetry. We successfully excised Bruun's cyst located in the bladder neck using a cystoscopic approach, allowing us to visualize the internal structure of the cyst. Results: Following the surgical removal of the Bruun's cyst, there was a significant decrease in the International Prostate Symptom Score, dropping from an initial value of 11 to a subsequent score of 5. Hematoxylin/eosin staining and GATA-binding protein 3 immunostaining were employed, confirming the presence of urothelial mucosa within the cystic specimen. Conclusion: Transurethral deroofing and cyst resection constitute an effective treatment approach for Brunn's cyst accompanied by LUTS.
