RESUMEN
Objective:To investigate the clinical safety and efficacy of robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty for ureteral stricture.Methods:The clinical data of 6 patients with ureteral stricture admitted to the Guizhou Provincial People's Hospital from December 2020 to August 2022 were retrospectively analyzed. There were 3 males and 3 females, with an average age of (40.2±11.5) years old. The status of ureteral stricture and hydronephrosis was measured by ultrasonography, CT urography and ureteral retrograde angiography. There were 2 cases of left ureteral stricture and 4 cases of right ureteral stricture, including 4 cases of upper segment stricture and 2 cases of middle segment stricture. The separation of the renal pelvis on the affected side was 3.2 (2.1, 4.2) cm. The length of ureteral stricture was 3.8 (2.5, 4.3) (1.0-5.0) cm, and the preoperative blood creatinine was 90(71, 97)μmol/L. Robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty was performed in all cases under general anesthesia. The strictured ureter segment was separated and longitudinally cut during the operation. The lingual mucosal grafts 2.5-5.0 cm in length and 1.0-1.5 cm in width was cut according to the stricture. Then the lingual mucosal grafts were harvested and placed in the strictured ureter as a ventral onlay. One double J tube was placed in the affected side in all cases during operation. The perioperative outcomes and complications were analyzed. The blood creatinine and renal pelvis separation on the affected side after surgery were compared with the preoperation.Results:All the surgeries were successfully completed. The average operative time was (190.8 ± 59.0) min, median blood loss was 40 (20, 63) ml, postoperative indwelling time of the drainage tube was 6 (4, 6) days, gastrointestinal function recovery time was 3 (2, 3) days, postoperative hospital stay was 6 (6, 7) days. The patients had clear pronunciation and lingual incision recovered 1 week post-operatively. The urine tube was removed 2 weeks after surgery, and the double J tube was removed 8 (6, 10) weeks post-operatively. Radiological examination revealed significant difference in hydronephrosis on the affected side 3 months post-operatively compared with the preoperation, and the separation of the renal pelvis on the affected side was 1.2 (1.2, 1.4) cm after surgery. The blood creatinine was 79(71, 104)μmol/L at 3 month after surgery, which was also improved compared with preoperative.Conclusions:Robot-assisted laparoscopic ventral onlay lingual mucosal graft ureteroplasty is a feasible and safe option for the treatment of ureteral stricture with less trauma, rapid recovery, and less complications.
RESUMEN
Ewing sarcoma is a member of the Ewing sarcoma family tumor(ESFT), which is commonly from bones and soft tissues, while it is rare for penis. In this thesis, a case of 21-year-old Ewing sarcomas on the left side of the penis was reported. After the penis mass excision, the pathological diagnosis was Ewing sarcoma and positive margin, then he underwent penis total hysterectomy. After the surgery, he received chemotherapy for 14 cycles without radiation. With 8 months’ reexamination and follow-up, there was no local recurrence or metastasis.
RESUMEN
Objective The pathogenesis of urinary tract infection and the preventive effect of Bacillus Calmette Guerin on bladder cancer imply the importance of bladder as a unique mucosal surface research. This article discussed that after bladder infected by bacteria,the way in which the microenvironment produce adaptive immunity. Once in the past, bladder is widely considered to be a sterile environment, the concept has been recently shaken. It is suggested that we should further study the influence of urinary tract pathogen infection or BCG immune response. In this paper, bladder biology has been illustrated, and bladder organ immunity is urgently needed to be explored and defined.
RESUMEN
Objective To investigate the clinical efficacy of selenium-enriched garlic on patients with oligoasthenospermia.Methods From October 2012 to August 2013,160 patients with oligoasthenospermia were randomly divided into two groups.Treatment measurements for 80 patients in the control group included oral treatment of Shengjing capsules 1.6 g/time Tid,Vit-E soft capsules 100 mg/time Tid,and took Vit-B 0.2 g/time Tid,for three months.Treatment measurements for 80 patients in the treatment group included oral treatment of selenium-enriched garlic in addition to all the above,for three months.We observed the changes of the semen quality indexes (including semen volume,sperm density,motility,survival rate,etc.) of two groups before and after treatment.Results Sperm quality was improved after treatment in both groups.All indices in the treatment group were significantly higher than those in the control group (P ＜ 0.05).Conclusions For patients with male infertility caused by oligoasthenospermia,The use of combination of selenium-enriched garlic and Shengjing capsules can improve the quality of sperm.
