Intermittent hydronephrosis may appear as acute abdominal pain. Between episodes of pain, the patient may be asymptomatic, and the intravenous urogram usually will be normal. The condition is diagnosed from intravenous urograms taken either during an episode of pain or after hydronephrosis has been precipitated by hydration. There are many causes of intermittent hydronephrosis; however, the closed renal pelvis and nondistensible ureteropelvic junction are important factors in nearly all cases. Pyeloplasty is the best treatment and is usually curative.
间歇性肾积水可能表现为急性腹痛。在疼痛发作间歇期，患者可能无症状，静脉肾盂造影通常也会正常。该病症通过在疼痛发作期间或通过水化诱发肾积水后进行的静脉肾盂造影来诊断。间歇性肾积水有多种原因；然而，闭合性肾盂和不可扩张的输尿管肾盂连接处几乎在所有病例中都是重要因素。肾盂成形术是最佳治疗方法，通常可治愈。
