Aim. To evaluate the results of different methods of urine derivation in patients with postrenal anuria due to upper urinary tract (UUT) obstruction, caused by fungal bezoar.
Materials and methods. The results of treatment of postrenal anuria in 8 patients without congenital obstructive anomalies of UUT in 5 clinics from 2004 to 2018 were analyzed. All patients from the birth received continuously two or more antibiotics for diseases not related to kidneys and the urinary tract. Median of gestational age was 32 weeks [31.5; 38.5]. There were 4 boys (50%), and 4 girls (50%). The duration of anuria at the time of hospitalization was 2 days [1.5; 5]. Creatinine level at admission was 218 µmol/l [164.5; 392.5] and urea was 17.9 mmol/l [13.2; 24.95]. In all cases, candida albicans was revealed in urine. Postoperative complications were graded according to the Clavien-Dindo classification.
Results. All patients received systemic antifungal therapy; UUT drainage was performed in 7 (87.5%) cases. Ureteral catheter was placed bilaterally in 2 (28.6%) patients (4 renal units). There were 5 complications (Clavien-Dindo grade IIIb). Bilateral percutaneous nephrostomy was performed in 3 (42.8%) patients (6 renal units), and there were 2 complications (Clavien-Dindo grade IIIb and V). Open pyelostomy was performed in 2 (28.6%) patients (one bilateral, one on the right side; a total of 3 renal units). There was only one complication of Clavien-Dindo grade V. The average number of surgical procedures required to alleviate UUT obstruction per one renal unit was as following: 2.25 for ureteral catheterization; 1.17 for percutaneous nephrostomy; 1 for open pyelostomy. Regardless of the drainage method, diuresis tended to be normalized and azotemia decreased during the first postoperative day. In one case, the obstruction was eliminated by antifungal therapy without drainage of UUT. Mortality rate was 25% (n = 2).
Conclusion. Ureteral catheterization is a minimally invasive, safe method for decompression of UUT obstruction, caused by fungal bezoar, which is non-inferior to nephrostomy tube or open pyelostomy. Ureteral catheterization can be used as a primary method of urine derivation in children with UUT obstruction caused by candida bezoar
