A Rare Cause of Macroscopic Hematuria: Ureteral Fibroepithelial Polyp: A Case Report

Abstract

Fibroepithelial polyps are rare, benign, non-epithelial tumors of the urinary system. They can occur throughout the entire urinary system, including the renal pelvis, ureter, bladder, and urethra, which are lined with urothelium. These polyps originate from the stromal structure, formed by the combination of mesodermal and urothelial cells. The most common clinical complaint of patients with fibroepithelial polyps is unilateral flank pain. In some cases, this pain may be accompanied by hematuria, dysuria, and pollakiuria, which are irritative lower urinary tract symptoms. In this case report, a case of a giant ureteral fibroepithelial polyp in a patient who was admitted to our clinic with macroscopic hematuria and left flank pain was presented. Following the diagnosis of a giant polyp in the left ureter, we treated the patient with endoscopic ablation using a Holmium-YAG laser device under ureteroscopy guidance.

Makroskopik Hematürinin Nadir Bir Nedeni: Üreteral Fibroepitelyal Polip: Bir Olgu Sunumu

Abstract

Fibroepitelyal polipler üriner sistemin oldukça nadir görülen, iyi huylu, epitelyal olmayan tümörleridir. Böbrek pelvisi, üreter, mesane ve üretra da dahil olmak üzere üroepitelyum ile döşeli, üriner sistemin tamamında ortaya çıkabilirler. Mezodermal ve üroepitelyal hücrelerin birleşiminden oluşan stromal yapıdan köken alırlar. Fibroepitelyal polipli hastaların kliniğe en sık başvuru şikayeti tek taraflı yan ağrısıdır. Bazı durumlarda yan ağrısına hematüri, dizüri, pollaküri gibi irritatif alt üriner sistem semptomları da eşlik edebilir. Bu olgu sunumunda, makroskopik hematüri ve sol yan ağrısı şikayetleri ile kliniğimize başvuran bir hastada dev üreter fibroepitelyal polip sunulmuştur. Sol üreterde dev polip tanısı konulan hastaya üreteroskopi eşliğinde Holmium-YAG lazer cihazı kullanılarak endoskopik ablasyon uygulandı.
