Check the temperature-pressure relief valve to insure that the valve has not become incrusted with lime. 检查降温减压安全阀是否被石灰堵塞。
Results and Conclusion After ESWL treatment, the incrusted double J stents were successfully withdrawn in all the 6 cases, without causing any morbidity related to the use of ESWL. 结果本组6例患者经ESWL治疗1~2次后,双J管均顺利拔除。
