Objective To explore the value of the ratio between inferior turbinate and nasal cavity morphology in the diagnosis and treatment of inferior turbinate hypertrophy.Methods The clinical and CT imaging data of patients with nasal septum deviation were retrospectively collected.Patients were divided into an inferior turbinate hypertrophy group(experimental group)and a control group without nasal congestion symptoms and related lesions.Based on CT imaging data,four ratios of inferior turbinate to nasal cavity morphology were calculated:inferior turbinate bone to nasal cavity width ratio,lateral mucosa of inferior turbinate to nasal cavity width ratio,medial mucosa of inferior turbinate to nasal cavity width ratio,and inferior turbinate to nasal cavity width ratio.A t-test was used to compare the four ratios between the experimental and control groups.Results The mean values of inferior turbinate bone to nasal cavity width ratio,lateral mucosa of inferior turbinate to nasal cavity width ratio,medial mucosa of inferior turbinate to nasal cavity width ratio,and inferior turbinate to nasal cavity width ratio at the uncinate process level in the experimental group were 0.344±0.046,0.101±0.031,0.108±0.031,and 0.244±0.043,respectively.In the control group,these ratios were 0.061±0.019,0.074±0.018,0.097±0.044,and 0.146±0.038,respectively.All four ratios were significantly higher in the experimental group than in the control group,with statistically significant differences(P＜0.05).The area under the curve(AUC)for diagnosing inferior turbinate hypertrophy using inferior turbinate bone to nasal cavity width ratio,lateral mucosa of inferior turbinate to nasal cavity width ratio,medial mucosa of inferior turbinate to nasal cavity width ratio,and inferior turbinate to nasal cavity width ratio were 0.870,0.907,0.884,and 0.926,respectively.Conclusion The ratios of inferior turbinate to nasal cavity morphology can serve as quantitative indicators for inferior turbinate hypertrophy,providing clinical value for treatment planning.

Pediatric calyceal diverticulum (CD) is a relatively rare entity. Fewer cases were reported in China treated by retroperitoneal laparoscoopic surgery in children. In this paper, 2 cases of children with CD admitted to our hospital were reported. CT urography showed cystic low-density mass without obvious enhancement, and delayed contrast agent was found to enter the lesion. Both cases underwent cystoscopy + retroperitoneoscopy + diverticular neck suture. They were followed up for 15 months and 9 months after the surgery, respectively, with favorable outcomes and no recurrence of CD.

Objective To evaluate different operative procedures for renal cell carcinoma. Methods 81 cases of renal cell carcinoma operated were reviewed.Radical nephrectomy was carried out for 73 case of which renal artery embolism was conducted for 38 before operation.Simple nephrectomy was carried out for 6 cases and enucleation of the tumor for 2. Results The pathological stu dies showed that 52 cases were clear cell carcinoma,19 cases of granular cell carcinoma,6 cases being a combination of the above two varieties,4 cases being cystic renal cell carcinoma.65 of 81 cases have been successfully followed up for 12～110 months.The 5 year survival rate for stage Ⅰ,Ⅱ,Ⅲ and Ⅳ tumors were 83.9%,78.9%,33.3% and 16.7% respectively. Conclusions Renal artery embolism before radial nephrectomy is essential for a successful operation to achieve a long term survival.Nephron sparing surgery for a small,localized low stage renal tumor is safe and effective.
