Urological complications after radical hysterectomy with postoperative radiotherapy and radiotherapy alone for cervical cancer

Radiotherapy is a reliable method to cure cervical cancer patients, but it could cause serious urological complications after the treatment due to the anatomical location of the cervix. The main purpose of this retrospective analysis is to study the incidence, latency, and therapeutic efficacy of urological complications caused by radical hysterectomy with postoperative radiotherapy or radiotherapy alone in patients with cervical cancer.A retrospective analysis was conducted on patients with cervical cancer who received radical hysterectomy with postoperative radiotherapy or radiotherapy alone at the First Hospital of Jilin University between January 2010 and May 2016. The urological complications were confirmed by clinical manifestation, ultrasound, computed tomography (CT), nuclear scintigraphy, and assessment of renal function. All the patients with urological complications received conventional treatment, including conservative, electrosurgery, ureteral stents, nephrectomy, and neoplasty. The onset time of radiation injury symptoms was confirmed according to the medical history and follow-up. The surveillance for the therapeutic effects for these complications was accomplished by cystoscopy, imaging, and laboratory assessment.The overall rate of urological complications after treatment was 3.26%, comprising 2.12% ureteral obstruction, 0.98% radiocystitis, and 0.16% vesicovaginal fistula. The incidence of ureteral obstruction in patients treated with radical hysterectomy with postoperative radiotherapy and radiotherapy alone was not statistically significant (2.18% vs 1.59%, P>.05). The median onset time of radiocystitis and ureteral obstruction was 10 months (0-75 months) and 12 months (2-66.3 months), respectively. The onset time of vesicovaginal fistula was 3.5 months. After the appropriate treatment, the majority of the complications were under control.The incidence of urological complications is acceptable. There was no statistical difference in the risk between patients treated with radical hysterectomy with postoperative radiotherapy and radiotherapy alone. The latency period between radiotherapy and the manifestation of urological complications may be relatively long. So it is crucial to underline long-term follow-up after radiotherapy. The majority of urological complications were alleviated after symptomatic treatment and the patients with cervical cancer achieved long-term remissions or cures.
