The two most common types of ureteroenteric anastomosis during the procedure are the refluxing Bricker and Wallace techniques.
The objective of the present study was to perform a meta-analysis of all studies that have compared ureteroenteric stricture rates between both surgical techniques.
Studies with comparative data between Bricker and Wallace ureteroenteric anasatomoses were eligible for inclusion.
The following information regarding each eligible trial was recorded: author names, journal, year of publication, study type, enrolment dates, length of follow-up, total number of patients, total number of ureters, patient demographics, history of radiotherapy, indication for ureteroenteric anastomosis, imaging modality for diagnosing ureteroenetric stricture, incidence of ureteroenteric stricture per renal unit (i.
Four published studies containing comparative data on Bricker and Wallace ureteroenteric anastomoses were identified (Table i).
All 4 studies included comparative data on the incidence of ureteroenteric stricture after Bricker and Wallace anastomoses (Table 2).
On random effects analysis of ureteroenteric stricture rate per ureter, the Bricker ureteroeneteric anastamosis was not associated with a significantly higher overall stricture rate compared to the Wallace ureteroenteric anastomosis (Fig.
A meta-analysis on the incidence of urinary tract calculi and tumour recurrence at the site of the ureteroenteric anas tomosis was not performed as no patients developed disease recurrence or calculi during the follow-up period.
Although Bricker and Wallace surgical techniques remain the two most common methods of ureteroenteric anastomosis for ileal conduit, there is little comparative data on their associated outcomes.
The Wallace ureteroenteric anastomosis was popular in the United Kingdom during the 1970s as it was technically easier, quicker, and less likely to precipitate ureteroenteric stricture disease as demonstrated Clark and colleagues in which the incidence of ureteroenteric stricture was 2% in 101 patients that were followed up to 12 years.
The main long-term complications of ileal neobladders are infections and stone formation, ureteroenteric
stricture, voiding dysfunction, metabolic abnormalities, tumours, and perforations.
