“…In recent years, the increasing use of transrectal ultrasound (TRUS) and computed tomography (CT) scans have resulted in the discovery of incidental prostatic cysts. Prostatic cysts are observed in 0.5% to 7.9% of patients and are classified into six distinct types [1]. Most prostatic cysts are asymptomatic and are located posteriorly.…”

An Anteriorly Positioned Midline Prostatic Cyst Resulting in Lower Urinary Tract Symptoms

et al. 2010

Most prostatic cysts are not symptomatic and are found incidentally. There have been some reports of prostatic cysts presenting as an infravesical obstruction. Our case is the second published report of an anteriorly positioned midline prostatic cyst of the bladder neck. The prostatic cyst in a 41-year-old man presenting with lower urinary tract symptoms was located in the anterior and midline area of the prostate and was protruding into the bladder neck at the precise twelve o'clock position. The cyst obstructed the bladder neck by acting like a checking valve. Transurethral resection of the cyst was performed, and the obstructive symptoms successfully improved. In recent years, the increasing use of transrectal ultrasound (TRUS) and computed tomography (CT) scans have resulted in the discovery of incidental prostatic cysts. Prostatic cysts are observed in 0.5% to 7.9% of patients and are classified into six distinct types [1]. Most prostatic cysts are asymptomatic and are located posteriorly. Symptomatic prostatic cysts may be confused with benign prostatic hyperplasia (BPH) or neuropathic bladder when they present with lower urinary tract symptoms (LUTS) [2]. Midline prostatic cysts are less common and are mostly located posteriorly. Treatment options for symptomatic midline prostatic cysts include transrectal aspiration, transurethral marsupialization, and open surgery [3]. Here we report on a single case of a midline prostatic cyst of the bladder neck in the precise twelve o'clock position. The prostatic cyst was located anteriorly and acted like a checking valve during urination. To date, there have been fewer than five published reports of cases of symptomatic midline prostatic cysts located anteriorly [3][4][5]. Some cases of infravesical midline prostatic cysts have been reported [6,7]. To our knowledge, this is the second published report of an anteriorly positioned midline prostatic cyst of the bladder neck [7] and the first case report of a prostatic cyst in Korea. CaseA 41-year-old man presented with LUTS, including dysuria, frequency, weak urine stream, and a sensation of residual urine that had appeared two weeks before. He had no previous medical problems and had been healthy. His International Prostate Symptom Score (IPSS) was 20, and his quality of life (QoL) score was 4. Uroflowmetry showed that the peak flow rate was 9 mL/s (136 mL voided volume) and the volume of residual urine was more than 200 mL. A digital rectal examination revealed a normal pros-

“…Fourteen (40%) patients complained of obstructive urinary tract symptoms, 11 (33%) of urinary retention, 3 (9%) of urodynia, and 2 (6%) of infertility. Galosi et al reported that midline cysts are observed by transrectal USG in 9.8% of cases [1]. Most midline cysts, however, are located posteriorly [6].…”

“…Galosi et al classified 6 distinct cyst types based on TRUS and pathological features, including midline cyst, cyst of the erectile dysfunction, cyst of the parenchyma, multiple cysts, complicated cyst, cystic tumor, and cyst secondary to other diseases. Three percent to 7.5% of asymptomatic patients have medial cysts, and 5% of patients have LUTS [1]. Tambo et al analyzed 34 patients with symptomatic cysts [5].…”

ÖzetProstat kistleri nadirdir. Çoğunlukla, asemptomatiktir ve prostat posterior alanın-dan köken alırlar. Anterior yerleşimli prostat kistleri posteriora göre çok daha seyrektir. Akut üriner retansiyon ile başvuran 41 yaşındaki erkek hastada prostatik kist saptandı. Kiste transüretral rezeksiyonu (TUR) yapıldı ve histopatolojik değer-lendirmede kolumnar epitel ve proliferatif ürotelyal astar ile kaplı bir benign kist olarak raporlandı. Özellikle obstrüktif alt üriner sistem semptomları olan genç erkeklerde prostat kistleri nadir görülür ve TUR ile prostat kist tedavisi oldukça başarılı sonuçlar alınan minimal invaziv bir yaklaşım gibi görünmektedir. Anahtar KelimelerKist, LUTS, Prostat, Akut Üriner Retansiyon Abstract Prostatic cysts are rare entities. Mostly, they originate from the posterior area of the prostate and asymptomatic. Anterior location of the prostatic cyst is rarer than posterior. The prostatic cyst in a 41 year-old man presenting with acute urinary retansion. Transurethral resection (TUR) of the cyst was performed, which revealed a benign cyst lined with columnar epithelium and proliferative urothelial lining on histopathological evaluation. Prostatic cysts particularly in young men with obstructive lower urinary tract symptoms are rarely seen. Management of the prostatic cyst with TUR seems to be a minimally invasive approach with successful outcomes.
