2024年12月13日 · What is ureteropelvic junction (UPJ) obstruction? Ureteropelvic junction (UPJ) obstruction is a blockage in the renal pelvis of your kidney. Each of your kidneys has a renal pelvis. The renal pelvis is located at the upper end of each tube that drains pee from your kidneys to your bladder (ureter).

2022年5月22日 · 当我们可以通过 puj 进行肾镜检查时，进行经皮肾盂切开术会更加舒适。这确保可以以受控方式进行内切开术切口，同时将镜头从输尿管上段缩回肾盂。然而，如果 puj 的口径太窄，那么进行肾盂切开术将具有挑战性，因为在所有情况下都可能无法使用传统的肾镜。

While not visible in the picture, the ureter immediately distal to the PUJ measured 4mm in diameter. This is an macroscopic example of chronic PUJ obstruction with marked hydronephrosis.

肾盂输尿管连接部梗阻 （UPJO，ureteropelvic junction obstruction）指肾盂至输尿管尿流输送功能的显著损害，大部分为先天性，但可能在成人后才有临床表现。 结石、术后或炎症狭窄、以及尿路肿瘤也可在临床上表现为UPJ处梗阻的症状和体征。 外压性梗阻也可在此处有类似表现。 本节主要谈及先天性UPJO的诊断和治疗，但这些技术也适用于如尿路结石等获得性UPJO。 发病机制. 先天性UPJO通常源于内在病变， 输尿管节段无蠕动 是常见表现，类似于 原发性梗阻性巨输尿 …

2025年3月3日 · Ureteropelvic junction (UPJ) obstruction or pelviureteric junction (PUJ) obstruction partially obstructs the passage of urine from the renal pelvis to the ureter. It is the most frequent cause of hydronephrosis in the fetus and can also present in adulthood.

2021年8月11日 · Pelvi-ureteric junction obstruction (PUJ) isn’t just a condition in babies; adults can experience it, too. If it isn’t tended to, it can lead to kidney damage.
