Abstract：
Giant bladder is a rare condition with varied definitions and causes. It can lead to complications such as urinary tract infections, retrograde urine reflux, pyelonephritis, renal damage and occasionally vascular obstruction. In this case report, we present a man in his 70s with massive urinary retention >7 L and severe bilateral hydronephrosis. The patient underwent a successful Greenlight photovaporisation of the prostate to address underlying bladder outlet obstruction. The surgical procedure resulted in significant improvement in urinary function, enabling the patient to live catheter and infection free, and without renal damage. This case demonstrates that bladder outlet surgery can be useful in selected cases of giant bladder to avoid complications of chronic catheterisation or ongoing retention.
摘要：
巨大膀胱是一种罕见的疾病，其定义和原因各不相同。会导致尿路感染等并发症,逆行尿液反流,肾盂肾炎,肾损害和偶尔血管阻塞。在这个案例报告中,我们介绍了一名70多岁的男子，患有大量尿潴留>7L和严重的双侧肾积水。患者接受了成功的前列腺绿光光汽化术，以解决潜在的膀胱出口梗阻。外科手术导致尿路功能的显著改善，使患者能够活导管和无感染，没有肾损伤.此病例表明，膀胱出口手术可用于选定的巨大膀胱病例，以避免慢性导管插入或持续保留的并发症。
