Introduction:
Obstructive uropathy in pregnant women is a relatively common condition. It can be difficult to assess due to the frequency with which physiologic dilation of the upper urinary tract is seen in pregnant women.
Patients And Method:
Over the past 3 years 40 pregnant women with symptomatic obstructive uropathy were seen in our service.
Results:
Most pregnant women responded to conservative treatment (pain killers and antibiotics). In the remaining group, instrumentation was necessary through the urinary route: double J ureteral catheterism (10 patients: 6 due to uterine compression and 4 to lithiasis), percutaneous nephrostomy (4 patients: 2 due to ureteral catheter obstruction impossible to replace, and two due to urinary sepsis), or ureterorenoscopy (1 patient with lithiasis).
Conclusions:
The single most common cause for obstructive uropathy in our experience is ureteral compression due to a gravid uterus. Choice therapy in most cases is conservative treatment. When in spite of conservative treatment signs and symptoms persist, urinary by-pass with antibiotic prophylaxis must be performed. Ureterorenoscpy as a diagnostic and therapeutical approach should be taken into consideration in pregnant women with ureteral lithiasis. Incidence of pre-term labour was not higher than usual.
