“…The former is within the 23-43% range reported in upper poles associated with ectopic ureters [5][6][7]. In keeping with the accepted embryogenetic theory proposed by Mackie and Stephens [16] in 1975, the degree of renal dysplasia would directly correlated to the degree of ureteral ectopia, the more ectopic the ureter the more severe the renal dysplasia.…”

Clinico-pathological correlation in duplex system ectopic ureters and ureteroceles: can preoperative work-up predict renal histology?

We did not find significant differences in the histology of upper poles associated with ectopic ureters and ureteroceles. Histology was normal in more than one-third of patients, although the poles were poorly functioning. We hypothesize that these poles were hypoplasic rather than dysplasic. We failed to identify predictors of histological damage. Hence, the latter cannot be considered a factor guiding our decision-making.

“…Human series showed a similar spectrum of histological lesions, with a prevalence of upper pole dysplasia ranging between 23 and 43% in ectopic ureters and 64 and 100% in duplex system ureteroceles (DSU), and normal histology being reportedly an exceptional finding [5][6][7][8][9][10].…”

“…Patients with ectopic ureters may present with infection, incontinence, hydronephrosis or refl ux. A bladder with ureteric ectopia can achieve normal bladder function and capacity along with normal transurethral voiding and satisfactory continence like our case [10] . Incontinence in association with an ectopic ureter does not occur in the male because the opening of the ureter is mostly proximal to the external sphincter.…”

“…There are many studies dealing with evaluation of histological findings in Up specimens after UpN in the case of ureteroceles or ectopic ureters in duplex kidney 1,3,4,[13][14][15] . However, only little attention has been dedicated to the predictive value of preoperatively collected records for the presence and severity of histological lesions in this situation [16][17][18] .…”

“…The choice of proper medical treatment of ureteroceles or ectopic ureters in the duplex kidney remains a challenge despite the availability of several studies addressing this problem [1][2][3][4][5][6] . in current practice, treatment is based on morphological information from ultrasonography (Us), information about function from the dimercaptosuccinic acid (dmsa) or mercaptoacetyltriglycine (maG-3) renal scan, and the clinical course.…”

Aim. To assess of the role of renal ultrasonography (US) and DMSA renal scintigraphy in the prediction of irreversible histological lesions of the upper pole in duplex system. Methods. A prospective cohort study based on data collected between 2005 and 2012 at our institution. The cohort consisted of 23 patients with ureteroceles and 28 patients with ectopic ureters who underwent upper pole nephrectomy. Preoperative recordings from ultrasound and nuclear renal scans were compared with the histological findings. Histological irreversible lesions were defined as the presence of dysplasia and/or severe chronic interstitial nephritis (CIN) in ≥ 90% of the specimen. ROC (Receiver Operating Characteristic) curves were used to investigate thresholds in order to identify irreversible lesions using various differential functions. The histology was correlated with the results of imaging. Results. Pathological findings were found in all histological samples. Histological lesions were irreversible in 20/23 patients (87.0%) with ureteroceles and in 14/28 patients (50.0%) with ectopic ureters. The model is able to predict irreversible lesions if an upper pole differential function is ≤ 3% in patients with ureteroceles, and ≤ 2% in the presence of ectopic ureters. Weak association between parenchymal thinning on ultrasonography and irreversible lesions was found in patients with ectopic ureters. Conclusion. DMSA renal scintigraphy provides a useful tool for the prediction of irreversible lesions in the upper pole. Low differential function (≤ 3% and ≤ 2%, respectively) indicates irreversible lesions, favoring heminephrectomy. Higher differential function indicates greater remaining biological potential of the parenchyma, favoring reconstruction of the upper pole.
