Abstract
The present study was conducted on sixty-two patients with
seventy-six benign ureteral strictures in department of Urology
Benha Faculty of Medicine.
This study was limited to treatment of strictures involving the
ureter. Strictures of pelviureteric junction and ureteroilial anast-omosis were excluded because these may represent a different pathogenic process.
A detailed history was taken from every patients particularly past history for detection the aetiology of ureteral strictures. All patients were subjected to preoperative clinical examination and laboratory investigation as well radiological assessment by plain x-ray, intravenous urography and ultrasonography. Retrograde uro-graphy was performed in 32 strictures, antegrade urography was performed in 8 strictures and radionuclide renography was performed in 5 equivocal uretral strictures.
Different approaches were used for management of benign ureteral strictures through antegrade approach in 8 strictures, retrograde approach in 63 strictures, while combined antegrade and retrograde approach were performed in 5 strictures. When the ureteric orifice could not be detected or negotiated by the guidewire.
Summary
161
Different endourological techniques were randomly selected
for management of benign ureteral strictures. Teflon dilators were
performed in 15 strictures (19.7%), 28 strictures (36.8%) were
treated by balloon dilatation, cold knife endoureterotomy were
performed in 14 strictures (18.4%) and in 19 strictures (25%)
balloon dilatation was performed after endoureterotomy.
After endourological management of ureteral strictures open tip ureteral catheter was left for 1 week in 42 strictures (55.3%) while in 34 strictures (44.7%), double-J catheter were left for 4 to 6
weeks.
All patients were evaluated after removal of the stent at 3 to 6 months interval. It is considered to be successfully managed by decrease or obscent of previous complaints, decrease of the degree of hydronephros is and dilatation of strictured area.
Out of 76 managed benign ureteral strictures with follow up period ranged from 3 to 18 months, 48 strictures (63.2%) were successfully treated, while 28 strictures (36.8%) failed.
-There were no statistical significant correlation between success rate and aetiology or location of ureteral strictures.
-The higher success rate was obtained after endourological management of strictures less than 1 cm. in length.
Summary 162
- There were statistically significant relation between results and
endourological techniques, where best success rate (84.2%) was
obtained by using cold knife endoureterotomy followed by
balloon dilatation and lifting double-J catheter for 4 to 6 weeks.
- The complications of endourological management of benign ureteral strictures were minimal and not serious in the form of
post operative infection in (6 cases), small perforation in (3
cases). Mild haematuria occurred in one case and subside spontaneously, restrictures in (5 cases) which were remanaged endourologically, and open surgical interference was not indicated for management of these complication.
