The diagnosis of EDO is based on patient's history, semen analysis (hypospermia, azoospermia, low fructose level), and transrectal ultrasound (TRUS), which can demonstrate seminal vesicle(s), vas ampulla(s) and/or ejaculatory duct(s) dilatation, Müllerian or utricular cyst, and ejaculatory duct(s) or seminal calcification(s). Confirmation of the suspected diagnosis, if needed, requires classical vasography or TRUS-guided seminal tract puncture and vesiculography. Treatment is usually successfully achieved with transurethral endoscopic procedures: retrograde ejaculatory duct(s) catheterisation, dilatation, incision or resection; seminal tract endoscopy is seldom performed.

{"title":"Treatment of the neonatal and infant megaureter in reflux, obstruction and complex congenital anomalies.","authors":"T P de Jong","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Controversy exists about the timing of surgery in neonates and infants with congenital anomalies such as refluxing and/or obstructing megaureters and ectopic ureteroceles. Discussion acuminates to the fact whether or not early reconstruction causes irreversible damage to the urodynamic properties of the bladder. Between 1986 and 1992, 49 neonates and infants with obstructing or refluxing megaureters and 23 neonates and infants with ectopic ureteroceles have been operated in our hospital with a mean follow-up of 7.3 years. Reimplant surgery consisted of a modified Politano Leadbetter procedure, ureterocele surgery consisted of complete excision of the ureterocele, including the urethral part, with reconstruction of the urethra, bladder neck and bladder base combined with ureteral reimplants. Urodynamically no unexpected changes or deteriorisation have been seen in any of the patients. Bladder capacity for age, especially in the reflux group, averages 200%. Two of the ureterocele patients needed clean intermittent catheterisation for several years. Results of reflux cure in megaureter surgery were disappointing in ureters with a flat diameter between 6 and 9 mm's that were not recalibrated leading to the conclusion that in young children recalibration of the distal ureter should be done from 6 mm's upwards. No post-operative ureteral obstruction was observed in any of the cases. The conclusion is that early major reconstructions of the lower urinary tract causes no specific harm to the urodynamic properties of the bladder and pelvic floor, provided that the surgery is performed by specialised pediatric urological surgeons. The reported urodynamic problems in this patient group are probably related to lack of experience to deal with dysfunctional voiding habits that are quite common in these children, also after successful surgery. These micturation problems are not related to the surgical procedures, they are the result of pre-existing urodynamic changes of bladder function in these children.</p>","PeriodicalId":75424,"journal":{"name":"Acta urologica Belgica","volume":"65 2","pages":"45-7"},"PeriodicalIF":0.0,"publicationDate":"1997-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20229054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean follow-up in the series is 36 months (24-36). 39 patients treated before radical prostatectomy by hormonotherapy or surgery (TURP, TULIP) were excluded from analysis. 28 patients treated with immediate adjuvant therapy were also excluded from the study on risk factors of recurrence. Clinical understaging is 37% (50/134 patients with stage T1-T2 have extracapsular extension or invasion of seminal vesicles). Preoperative PSA value is related to the pathologic stage. Extracapsular disease was found in 17% and 46% when PSA was < 4 ng/ml or > 10 ng/ml respectively, thereby confirming the poor staging value of preoperative PSA alone. Analysis of the surgical margins demonstrates a statistically significant difference (p = 0.018) between patients with a preoperative PSA < 10 ng/ml (22% of positive margins) and those with a PSA > 10 ng/ml (42% of positive margins). Predictive factors of recurrence were analyzed in the 112 patients who have not received pre- or postoperative treatment. The respective impact of clinical stage, preoperative PSA value, Gleason score, invasion of prostatic apex, capsular perforation, surgical margins, invasion of seminal vesicles or of pelvic lymph nodes, and invasion of intraprostatic, intracapsular or extraprostatic nerves were evaluated. In T3 cases, we observe 50% recurrence (but only 4 patients fall into this group) versus 14% in clinically localized tumors (T1c-T2c). No recurrence is detected when preoperative PSA is < 4 ng/ml; on the contrary 21% of patients with a PSA > 10 ng/ml recurred. Infiltration of the apex does not influence prognosis. In our experience, capsular perforation is a worse prognostic factor than positive surgical margins, the respective rate of failure being 25% and 17% respectively. Invasion of extraprostatic nerves increases the risk of failure compared to capsular perforation alone (31% vs 18%). Seminal vesicles invasion significantly worsens prognosis (50% vs 13% recurrence respectively; p = 0.024).
