Primary obstructed megaureter (POM) in children.
The aim of this study was to analyze the results of surgical and conservative treatment of non-refluxing POM. In the period 2000-2009, 45 children (52 ureters) were treated, the average age was 5.8 months (±10.33), 24 children (26 ureters) by surgery (I) and 21 children (26 ureters) by conservative means (II). The average follow-up period was 73.8 (±32.91) and 30.85 months (±23.1) resp. Urine examination, USG, DTPA99mTc, biochemical testing, micturating cystouretography in all patients were performed. Significant difference was present in the occurrence of hydronephrosis of 0th, 3rd and 4th grade, p10 mm, p<0.01; and in the occurrence of normal and prolonged time T ½, p<0.01. The health condition was adjusted in 13 (54.20 %), improved on DTPA99mTc in 5 (20.85 %), non-improved in 3 (12.50 %), deteriorated in 1 (4.15 %) and unknown in 2 (8.3 %) patients. In the IInd group a significant difference was in case of occurrence of hydronephrosis of 0th, 2nd and 3rd grade, (p<0.01, or p=0.037 and p=0.011) and in occurrence of normal ureter, with ureter 0-5 mm and dilated ureter 5-10 mm, p<0.01. The condition at the end of the follow-up period was assessed DTPA99mTc as adjusted in 11 (52.39 %) patients, improved in 6 (28.57 %), unimproved in 3 (14.28 %) and no patient was assessed as having deteriorated and unknown in 1 (4.76 %).


CONCLUSIONS
In patients with an impaired separate kidney function, early surgical treatment helps to minimize damage to the kidney function and prevents future complications (Tab. 6, Fig. 3, Ref. 32).
