Ureteroscope/flexible combined with balloon in the treatment of ureteral stricture with stones in transplanted kidney: a report of 9 cases in a single center / 现代泌尿外科杂志

【Objective】 To evaluate the efficacy and safety of ureteroscope or flexible ureteroscope combined with balloon dilatation in the treatment of ureteral stricture with renal calculi in transplanted kidney. 【Methods】 The clinical data of 9 patients treated in our hospital during 2016 and 2022 were reviewed. The changes of the width of hydronephrosis, levels of creatinine and urea nitrogen, reoperation, and re-dwelling of stents were analyzed. 【Results】 One patient failed the operation because the guide wire could not be inserted, and the other 8 patients successfully completed the surgery. The stents were removed 6 to 8 weeks after surgery. During the follow-up of 8 to 48 months, no recurrence of renal calculi occurred; 5 patients had no recurrence of ureteral stricture; 3 patients (cases 4, 6, 9) underwent regular ureteral stent replacement due to hydronephrosis; the width of hydronephrosis, creatinine and urea nitrogen levels of 8 patients were significantly improved (P<0.05). 【Conclusion】 Ureteroscope/flexible with balloon dilatation is safe and effective in the treatment of transplanted kidney with ureteral stricture and kidney stones.

Research on relationship between acute mountain sickness and geographic factors in young male / 局解手术学杂志

Abstact:Objective To study the relationship between acute mountain sickness and geographic factors in young males,and provide no-vel materials for screening susceptible population and exploring novel research ideas and methods. Methods Total 294 young men came from low altitude were randomly selected,questionnaire was conducted and military AMS standard was applied for diagnosis. Binary logistic re-gression was used to analyze the relationship between 10 different geographical factors and AMS incidence and figure out the risk factors for medical geographical differences of AMS. Results AMS incidence was 52. 04% (153 people),with most commonly seen dizziness,head-ache,shortness of breath,chest tightness and lip empurples,the occurrence was 89. 54%,84. 31%,66. 01%,65. 36% and 60. 78%,respec-tively. Binary logistic regression analysis revealed that altitude was the only geographical risk factor (OR=0. 998,P<0. 05). Conclusion Among the population who entered plateau,lower native altitude they used to live brings higher risk of AMS,therefore corresponding preven-tions should be adapted for those who come to high altitude from low altitude in order to ensure their health and safety.
