Adult bilateral non-obstructing orthotopic ureteroceles with multiple calculi: endoscopic management with review of literature

We describe and report two cases of bilateral symptomatic ureterocele with calculi in two young adult women. They were successfully managed endoscopically by a transverse meatotomy and stone extraction done bilaterally in a single operative session. The 6th month postoperative voiding cystourethrogram showed no reflux. The literature regarding the incidence, occurrence, diagnosis and management of this uncommon condition in adults has been reviewed and discussed.     

Adenonocarcinoma of the Urinary Bladder Mimicking Simple Ureterocele. A Case Report

We report a case of adenocarcinoma of the urinary bladder, mimicking simple ureterocele in a 55-year-old man, presenting irritative bladder symptoms. The literature review highlights the rarity of such tumor. Intravenous urography showed a dilated terminal portion of the left ureter resembling a cobra-head appereance. Cystoscopy revealed suspicious hyperemic lesion on the mucosa of the dilated terminal portion of the left ureter. Transurethral biopsy of the lesion was performed and pathological examination revealed a muscle-invasive adenocarcinoma. There were no metastatic lesions on computed tomography. The patient underwent radical cystectomy and urinary diversion.     

经尿道电切治疗输尿管口囊肿18例报告

目的探讨经尿道电切治疗输尿管囊肿的临床效果。方法回顾性分析18例输尿管囊肿的临床资料。结果 18例均一次手术治愈。随防6个月～3年,效果良好。所有患者均未见囊肿复发,无管口狭窄及返流。结论经尿道输尿管囊肿的腔内手术疗效显著,减少了手术创伤及术后并发症,缩短了手术及住院时间,是目前治疗输尿管囊肿的首选方法。     

经尿道内腔镜治疗输尿管囊肿(附15例报告)

目的：探讨输尿管囊肿的诊断和经尿道输尿管囊肿内镜下治疗方法。方法：15例患者均于术前明确诊断，其中膀胱镜诊断准确率100．0％、IVU诊断率80％、B超诊断率83．3％，均行经尿道输尿管囊肿内镜下切开或去顶术。结果：平均手术时间64．5min，术后平均住院3．5d，其中3例门诊治疗，未住院。术后平均随访16．5个月，效果良好，未见返流发生。结论：B超结合IVU、膀胱镜检查可以提高确诊率。输尿管囊肿治疗以经尿道输尿管囊肿切开或去顶术可以减少手术创伤及术后并发症，缩短手术及住院时间，可以作为输尿管囊肿的首选治疗方法。     

经尿道电切治疗输尿管囊肿19例体会

目的探讨经尿道电切(TUR)治疗成人输尿管口囊肿的临床疗效。方法采用TUR治疗成人输尿管口囊肿19例进行临床分析。结果 19例手术均一次成功,手术时间10～30min,随访6～36个月,效果良好。所有患者均未见术后大出血、囊肿复发、输尿管开口狭窄及返流等并发症。结论经尿道输尿管囊肿壁部分切除术是一种操作简单、手术时间短、创伤小、术后恢复快、并发症少、疗效确切的治疗手段。是目前治疗输尿管囊肿的首选方法。     

Experience with a novel approach to upper-pole nephrectomy and partial ureterectomy

The upper-pole moiety of a renal duplication anomaly associated with an ectopic ureter or ureterocele is often hydronephrotic and non-functioning. Thus, the treatment of choice is frequently upper-pole nephrectomy and partial ureterectomy. Previous surgical techniques have emphasized the initial removal of the upper pole followed by partial ureterectomy. The approach described here begins by identifying and dissecting the obstructed upper-pole ureter, dividing it distally, and performing the partial nephrectomy last. We have performed this procedure on 12 consecutive nonfunctioning and obstructed upper-pole moieties of duplicated kidneys. In 10 patients the obstructed upper pole was associated with an ectopic ureter or an ectopic ureterocele (bilateral in 1) and in 1 with uretero-pelvic junction obstruction of the upper-pole moiety. This anatomic approach has resulted in preservation of function in all 12 remaining lower renal and ureteral units as assessed by postoperative intravenous urography. Only 1 patient required an intraoperative blood transfusion. We believe that this safe and easy-to-teach approach should be included in the urologic armamentarium.     

Prenatal complicated duplex collecting system and ureterocele—Important risk factors for urinary tract infection

Purpose

To evaluate the risk of urinary tract infections (UTIs) in infants with prenatally detected complicated duplex collecting system (CDS) or ureterocele.

输尿管囊肿的诊断与治疗（附12例报告）

目的探讨输尿管囊肿的诊断及治疗方法。方法回顾性分析12例输尿管囊肿的临床资料。行耻骨上经膀胱输尿管囊肿切除同时行输尿管膀胱抗反流吻合2例,行经尿道输尿管囊肿切开或去顶治疗8例,行单纯囊肿切除黏膜下隧道成形术（Mason术）2例。结果12例患者治愈,随访1～3年无并发症发生。结论经尿道手术治疗输尿管囊肿是一种简便和有效的治疗方法。
