Villous adenoma of the urachal remnant: A diagnostic conundrum

Villous adenoma is a rare pathology seen in the urinary tract; it is mostly found in the large bowel. When encountered in the urinary tract, it mainly originates from intestinal segments of urinary reconstruction. Villous adenoma is commonly seen in patients more than 50 years and has a male predominance. In the urinary tract, it has been reported in the urachus, bladder dome and trigone. A few cases of villous adenoma have been described in the literature. We report a case of primary villous adenoma in the remnant of the urachus and discuss the pathophysiology, investigation and management.

Background: Urinary tract infection (UTI) is one of the most common bacterial infections seen in children. A wide range of organisms with varying antibiotic sensitivity patterns have been known to cause UTI. The objective of the study was to analyse the clinical presentation of UTI in children between 1-month to15 years of age and to analyse the causative microorganism and their drug susceptibility in UTI in children between 1 month to 15 years of age.Methods: A retrospective study was conducted in a teaching hospital in Kerala, between July 2018 and June 2020 among children 1 month to 15 years of age who presented with symptoms of UTI. Patients who had culture positive UTI were included in the study. Clinical data was obtained from inpatient and outpatient records. Antimicrobial susceptibility was done for positive urine culture by Kirby-Bauer disk diffusion method. Statistical analysis was done using Statistical package for social sciences (SPSS) software version 16.Results: Of the 1057 urine samples analysed, 18.44% had significant bacteuria. 43.07% were children less than one year of age with male predominance. Fever and dysuria were the most common clinical presentation. E. coli was the most prevalent pathogen isolated followed by Klebsiella pneumoniae. Enterococcus faecalis was the only gram-positive bacilli isolated. Highest resistance was shown to ampicillin, third generation cephalosporins and co-trimoxazole. Least resistance was shown to nitrofurantoin, fluoroquinolones, aminoglycosides, piperacillin- tazobactam and carbapenems.Conclusions: Regular surveillance programme is necessary for implementation of guidelines for empiric treatment of UTI.

Urinary Reconstruction

Urinary reconstruction is tempting based on the impressive abnormal findings that are revealed on imaging. The abnormal appearance of the urinary system by itself is not enough to warrant reconstruction. Reconstruction should only be undertaken when there is clear clinical evidence that stagnant urine leads to urinary tract infections and/or obstruction that is associated with renal compromise. This chapter describes temporary and permanent upper and lower urinary reconstructions. Particular consideration is given to the pathophysiology of prune belly syndrome and the disproportionate dilation and dysfunction of the distal ureter when undertaking ureteral remodeling. The techniques of ureteral folding and formal excisional ureteral tapering are described stressing the importance of vascular preservation. The role of reduction cystoplasty is placed in perspective of short- and long-term benefits. This review contains 18 references. Key Words: Eagle-Barrett syndrome, megacystis, megaureter, prune-belly syndrome, tapered ureteral reimplant, triad syndrome, ureteral reconstruction, urinary diversion, bladder reduction.
