[Symptomatic hydronephrosis during pregnancy].
OBJECTIVE
Hydronephrosis is common during pregnancy, affecting 90% of pregnant women. It is usually asymptomotic, but a small percentage of patients show clinical symptoms requiring treatment. We want to report our experience in the diagnosis and treatment of symptomatic obstructive uropathy in pregnant women.


METHODS
We retrospectively evaluate the results obtained in 162 pregnant women suffering symptomatic hydronephrosis who received care at our department over the last 12 years.


RESULTS
Conservative treatment was effective in most patients, 39 patients required more aggressive therapy. Thirty-five patients underwent insertion of a doubleJ catheter, 2 patients percutaneous nephrostomy, and another 2 ureteroscopy and extraction of ureteral lithiasis.


CONCLUSIONS
The most frequent etiology of symptomatic hydronephrosis during pregnancy is external compression by the gravid uterus, followed by ureteral lithiasis. We consider conservative treatment as the treatment of choice, leaving ureteral double J cotheter insertion or percutaneous nephrostomy for the refractory cases. Ureteroscopy is a new diagnostic and therapeutic option when other less aggressive meosures fail.
