Case summary
- A 74-year-old female had cervical cancer post radical hysterectomy,
lymphadenectomy and salpingo-oophorectomy. Bilateral ureter stricture
with regular double-J catheter revision was impressed. The latest
bilateral double-J catheter revision was performed three months ago.
Abdomen computational tomography revealed persistent bilateral
hydronephrosis (Fig 1). Thus, bilateral double-J revision was
performed. Cystoscopy shown turbid urine with right double-J catheter
dislodged. After replacement of the right double-J catheter, pus like
material effluxed from side hole of double-J stent which confirmed the
diagnosis of pyonephrosis (Fig 2, Video).
- Pyonephrosis is an infectious disease usually accompanied with
obstructive hydronephrosis, causing suppurative destruction of the
renal parenchyma. Retrograde ureteric stent is a good choice for
drainage of pyonephrosis other than percutaneous nehrostomy and
nephrectomy [1].
