We investigated postoperative hydronephrosis in 50 patients (100 ureter) undergoing radical hysterectomy for uterine cervical cancer from Jan. 1989 to Dec. 1991 at Department of Obstetrics and Gynecology in Nagasaki University Hospital.
The incidence of hydronephrosis was 68.1% of patients, and hydronephrosis was seen significantly more frequently and was of a higher grade on the right kidney than the left. After one year, hydronephrosis disappeared in 59.1% of patients (65.1% of right kidney, 88.2% of left kidney), and only 2 of 93 kidney have worsened.
In cases without hydronephrosis, hydronephrosis developed in only 3 of 31 kidney after one year due to local recurrence or nodule metastasis of the original disease.
We compared therapeutic effects of 3 methods (ureteral stent, PNS, no treatment). But there was no significant difference between these methods, we could not determine which was the best treatment. And we observed that indwelling ureteral stent might interrupt spontaneous healing of ureter.
Radiotherapy didn't significant influence hydronephrosis after radical hysterectomy;
Therefore, we suggest that, in patients with hydronephrosis without other severe urological complications after radical hysterectomy, clinical course should be observated for at least one year, first and them some treatments should be applied if cases worsen gradually than before.
