To describe 8 additional cases of seminal vesicle cyst associated with renal agenesis, an uncommon condition arising from anomalies occurring during embryonal development of the genitourinary system, and to analyze the utility of the different diagnostic imaging techniques.
A retrospective study was conducted on 8 patients to determine the diagnostic possibilities of US (abdominal/transrectal), CT, MRI, urography, cystourethrography and cystoscopy. Transvesical percutaneous punction and deferentography, which permit diagnosis of blind-ending ureter, were utilized in two patients.
75% were left-sided and the age at presentation was generally between 25 to 45 years. The clinical features were related with irritative voiding symptoms, perineal discomfort and ejaculatory disorders. Treatment was based on the clinical features; 3 patients underwent resection via the abdominal retrovesical approach and 5 patients were treated conservatively.
Congenital seminal vesicle cyst may not be as uncommon as it is presumed to be and should be suspected in patients with solitary kidney and voiding disorders. The findings on pelvioabdominal US may suffice to suspect this condition. Although many diagnostic imaging techniques are available, blind-ending ureter can only be diagnosed by transvesical or transrectal percutaneous punction and deferentography. Treatment of symptomatic cases is by surgery, although conservative treatment is utilized more frequently.
描述另外8例与肾缺如相关的精囊囊肿病例，这是一种由泌尿生殖系统胚胎发育异常引起的罕见病症，并分析不同诊断成像技术的效用。
对8例患者进行回顾性研究，以确定超声（腹部/经直肠）、CT、MRI、尿路造影、膀胱尿道造影和膀胱镜检查的诊断可能性。两名患者采用经膀胱经皮穿刺和输精管造影术，以诊断盲端输尿管。
75%为左侧，发病年龄一般在25至45岁之间。临床特征与刺激性排尿症状、会阴不适和射精障碍有关。治疗基于临床特征；3例患者通过腹部膀胱后入路进行切除，5例患者接受保守治疗。
先天性精囊囊肿可能并不像人们认为的那样罕见，对于单肾和排尿障碍患者应怀疑此病。盆腔腹部超声检查结果可能足以怀疑此病。虽然有许多诊断成像技术可用，但盲端输尿管只能通过经膀胱或经直肠经皮穿刺和输精管造影术诊断。有症状病例的治疗方法是手术，尽管保守治疗更常用。
