STUDY GF MEGALOURETER

Abstract

A 24 aged male patient with Megaloureter has been reported who has,
1) divertikel-like opened ureteral orfice and absence of its peristalsis,
2) vesicoureteral reflux,
3) dilated and meandered ureter,
4) dilated pelvis and bladder,
5) Renal disturbance.
Resection of distal segment of ureter about 7cm and ureterovesicoanastomose have been resulted in the disapearence of vesicoureteral backflow, markedly improvement of renal function, and radical cure of pyelitis. Till this time (One half year after the operation) the patient is not complaining.
Histo-pathological examination of excised ureter has demonstrated the absence of ganglion cell, as Swenson has described. Accordingly it is conceivable that the disease occure from the asthenic dilatation due to congenital absence of parasympathetic nerve in distal end of ureter and adjacent area of bladder wall.
