Introduction: Fibroepithelial polyps of the ureter are rare. Cases and small series are reported in the literature. The treatment of choice, outcome and appropriate follow-up regimen remain unclear. Methods: We conducted a systematic literature review of papers reporting fibroepithelial polyps of the ureter in adult patients. Articles published before 1980 were excluded. Results: The search yielded 144 papers, of which 68 met the inclusion criteria. A reference scan from the included 68 yielded an additional 7 new articles. In total, our study included 75 articles (68 + 7). A total of 134 patients were described. Most patients had a single lesion (range: 1-10). The median length of the polyp was 4.0 cm (range: 0.4-17.0). The percentage of polyps resected endoscopically increased from 0% before 1985 to 67% after 2005. Two perioperative complications were reported in 72 procedures (2.8%): a deep venous thrombosis and a case of mesenteric lymphadenopathy. Both of these occurred after open surgery. Follow-up data were available for 57 patients. The median follow-up was 12 months (range: 1-180). Four patients (7.0%) developed recurrent complaints: 2 had urinary stones, 1 had a ureteral stricture and 1 had recurrence of the polyp. Three of these events followed endoscopic resection, and occurred within a year after the procedure. Conclusion: Endoscopic resection of fibroepithelial polyps seems to be safe and effective. It is minimally invasive and should be considered the gold standard where endoscopic expertise is available. We advise follow-up imaging by computed tomographic intravenous urography after 3 months and ultrasound after 1 year to detect late complications.

Özet GirişÜriner sistem fibroepitelyal polipleri çocuklarda çok nadir görülen benign lezyonlardır. Bu lezyonların renal pelvisten, anterior üretraya kadar üriner sistemin her yerinde görülebileceği bildirilmekle birlikte, en sık üreteropelvik bileşkede ve prostatik üretrada görülmektedir (4,6) . Alt üriner sistemdeki fibroepitelyal polipler kendini sıklıkla idrar yapmada zorluk, azalmış idrar akımı, mesanenin yetersiz boşaltımı ve üriner retansiyon ile gösterir (8) .Mesane boynundan kaynaklanan polipler sıklıkla mesane içine doğru uzanıp büyük çaplara ulaşabilirler. Fibroepitelyal polipler benign mezodermal kitlesel lezyonlar olmasına karşın, lokalizasyonları nedeni ile sıklıkla rabdomyosarkom gibi mesanenin malign mezenkimal neoplazmları ile karışabilirler. Bu çalışma-da üriner retansiyon nedeniyle başvuran ve yapılan tetkiklerinde rabdomyosarkom ön tanısı alan, mesane boynu kökenli dev bir fibroepitelyal polip olgusu sunulmaktadır. Olgu SunumuDokuz aylık erkek hasta üriner retansiyon nedeni ile acil servise başvurdu. Hastanın öyküsünde daha önce üç kez mesane katetirizasyonu gerektiren idrar retansiyonunun olduğu öğrenildi. Hastanın fizik muayenesinde glob vezikale saptandı. Ultrasonografisinde; mesane içerisinden mesane boynuna doğ-ru uzanım gösteren, geniş, sınırları düzgün olmayan lobüle konturlu kitle tespit edildi. Bu bulgular rabdomyosarkomu düşündürmekteydi. Hastanın yapılan sistoskopisinde mesanenin tamamına yakın kısmını dolduran ve mesane boynundan kaynaklanan polipoid kitle saptandı. Mesane boynuna yapışık olan geniş tabanlı kitlenin mesane mukoza ve submukozasından kaynaklandığı ve mesane çıkışını tıkadığı izlendi. Sistoskopik bulgularla olası mezenkim kaynaklı bir neoplazm olacağı düşüncesi ile açık cerrahiye geçil-mesi kararlaştırıldı. Kitle suprapubik yaklaşımla total olarak rezeke edildi (Resim 1). Makroskopik olarak kitlenin 4x2,5x1,5 cm boyutlarında, düzgün yüzeyli

Ureteral polyps are a rare cause of ureteral obstruction in the adult and pediatric populations. Fibroepitheial polyps (FEP) are the most common type of ureteral polyps. This clinical entity is very rare, warranting periodic clinical review by practitioners, and new advancements in laparoscopy allow new surgical approaches to its cure. We present the case of a 20-year-old male with rightsided flank pain. He was found to have right uretero-pelvic junction (UPJ) obstruction and subsequently underwent laparoscopic robotic-assisted right collecting system exploration, excision of polyps and right ureteropyeloplasty. Ureteral polyps were excised and determined to be fibroepithelial in origin based on the pathological report. Our case highlights the importance of having FEP in the differential diagnosis of ureteral obstruction. We also found that laparoscopic robot-assisted polypectomy is a safe and acceptable surgical option for the excision of ureteral polyps.
