Vesical calculi refer to stones in the urinary bladder. The causes of bladder stones include bladder outlet obstruction, neurogenic voiding dysfunction, infection, or foreign bodies. Very rarely, these vesical calculi may reach very large sizes and the largest dimension can sometimes reach 13 centimetres.
This descriptive cross-sectional study was conducted from 1ST May 2019 to 31st October, 2019 at Institute of Kidney Diseases, Urology Department, Hayatabad Peshawar. 164 patients with vesical stone were included in study. Ultrasound-KUB was used for diagnosis of vesical stone and after informed consent, and they underwent transurethral nephroscopic lithotripsy via the pneumatic Swiss Lithoclast.
Frequency of stone clearance was 96.34%. No statistically significant association of stone clearance was observed with age, gender, number of stones or max dimension of largest stone in the bladder (p>0.05).
Transurethral nephroscopic pneumatic lithotripsy via pneumatic Swiss Lithoclast is safe and effective procedure for treatment of large vesical stones. However, this being the first such study in adults, more data is needed to confirm these findings.
膀胱结石是指存在于膀胱内的结石。膀胱结石的病因包括膀胱出口梗阻、神经源性排尿功能障碍、感染或异物。极少数情况下，这些膀胱结石可能长得非常大，最大尺寸有时可达13厘米。
这项描述性横断面研究于2019年5月1日至2019年10月31日在白沙瓦哈亚塔巴德肾病研究所泌尿外科进行。164例膀胱结石患者纳入研究。采用超声-KUB诊断膀胱结石，在获得知情同意后，患者通过气动瑞士碎石机接受经尿道肾镜碎石术。
结石清除率为96.34%。未观察到结石清除率与年龄、性别、结石数量或膀胱内最大结石的最大尺寸之间存在统计学显著关联（p>0.05）。
通过气动瑞士碎石机进行经尿道肾镜气压弹道碎石术是治疗大型膀胱结石的安全有效方法。然而，这是成人中的首例此类研究，需要更多数据来证实这些发现。
