Objective To assess the feasibility of intracavitary drainage using three equally-sized double pigtail stents in the treatment of ureteral stricture. Methods Placement of three identical double pigtail stents in ureters for indwelling for 10~12 weeks was carried out in 27 cases of ureteral stricture from March 2000 to June 2003. Results The patients were followed for 2~24 months, with a mean of 18 months. No lumbar distending pain or fever occurred after the removal of the drainage in 26 cases, with the IVP examination indicating patency drainage and no ureteral stricture. Re-examination of IVP 6 months after the surgery found no improvement of hydronephrosis in 1 case. The overall success rate was 96% (26/27). Conclusions Intracavitary drainage using three equally-sized double pigtail stents in the treatment of ureteral stricture is feasible.

Objective To evaluate the effect of intensity-modulated radiation therapy(IMRT) on parotid function in nasopharyngeal carcinoma(NPC). Methods Eighty-three NPC patients received prima-ry IMRT between 2001 and 2003. Xerostomia before radiotherapy, at the end of radiotherapy, at 6-month, 1-,2-,3-,4- and 5-year after radiotherapy were investigated, respectively. The relation between xerostomia and parotid dose distribution was analyzed. Results Of all the patients,4,31,31 and 17 had stage Ⅰ,Ⅱ,Ⅲ and ⅣA disease, respectively. Sixteen patients received chemo-radiotherapy. The median followed-up time was 65 months. The 5-year local control and regional control rate were 96% and 95% ,respectively. The 5-year overall survival rate was 80%. The mild xerostomia rate at the seven time points was 42%, 51%, 71%, 77%, 58%, 38% and 26%. The corresponding moderate xerostomia rate was 52%, 53%, 21%,8%, 3%, 2% and 2%, respectively. No serious xerostomia was observed. The mean dose of the bilateral parotid glands was 34.34 Gy. Xerostomia at 6-month after radiotherapy was positively correlated with the mean dose of the parotid glands, and D50 was the independent factor in predicting the xerostomia. Parotid function was well protected when the mean dose and D50 were no more than 33 Gy and 29 Gy,respectively. Conclusions IMRT can improve the local-regional control of NPC and protect the parotid glands from radiation-induced in-jury.

Objective To investigate the long-term outcome and prognostic factors of patients with nasopharyngeal carcinoma treated with intensity-modulated radiation therapy (IMRT). Methods From February 2001 to December 2006, 419 patients with nasopharyngeal carcinoma in Cancer Center of Sun yatsen University received IMRT. The number of patients with stage Ⅰ,Ⅱ,Ⅲ and Ⅳ disease was 28, 113, 202 and 76, respectively. In all, 182 and 237 patients received radiotherapy alone and chemoradiotherapy. The prescription doses were as follows:66-70 Gy/25 -30 f to GTV_(nx), 60 -64 Gy/25 -30 f to GTV_(nd), 55 -62 Gy/25 -30 f to CTV_1, and 42 -54 Gy/25 -30 f to CTV_2. Results The median follow-up time was 49 months (6 -94 months). The number of patients with follow-up of 1-, 3-, and 5-year were 419,360 and 166, respectively. Twenty-one, 13 and 57 patients had local recurrence, regional recurrence and distant metastasis, respectively. The 5-year local control (LC) rate, regional control (RC) rate and free from distant metastasis survival rate was 92.7%, 95.8% and 85.5%, respectively. The 5-year disease-free survival (DFS) and disease-specific survival (DSS) was 76. 3% and 84.4%, respectively. In univariate analysis, T stage, primary tumor volume, N stage and volume of cervical nodes before treatment were significant predictors of DFS and DSS, favoring the patients with early T stage (84. 1% vs. 67.6% ,Χ~2 = 12. 16, P = 0. 000 : 92. 1% vs. 75. 1% ,Χ~2 = 14. 86 . P = 0. 000) , primary tumor volume less than 20 cm~3 (89. 1% vs. 62. 9% ,Χ~2 =14. 13,P=0.000;96.2% vs. 72. 1% ,Χ~2 =38. 76,P=0.000), early N stage (81.1% vs. 64. 5%, Χ~2 = 15.49, P = 0. 000; 87. 8% vs. 76. 1%, Χ~2 = 10. 89, P = 0. 001) and volume of cervical nodes less than 5 cm~3 (83. 3% vs. 68. 8%, Χ~2 = 14. 13, P = 0. 000 ; 90. 0% vs. 78. 1%, Χ~2 = 10. 71 ,P =0. 001). Multivariate analysis showed that primary tumor volume (Χ~2 = 26. 81, P = 0. 000 and Χ~2 = 28. 47, P = 0. 000) and N stage (Χ~2 = 4. 92, P = 0. 026 and Χ~2 = 9.50, P = 0. 002) were independent predictive factors for both DFS and DSS. No grade 4 acute and late toxicities were observed. In 243 patients with follow-up time more than 3 years, only 2. 8% suffered from grade 3 late toxicifies. Conclusions IMRT with or without chemotherapy can improve the long-term survival of patients with nasopharyngeal carcinoma, especially in LC and RC. Distant metastasis becomes the main treatment failure. Primary tumor volume and N stage are significant prognostic factors. Acute and late toxicities are acceptable.
