Sponsored by Assiut University · Observational

The sponsor has not verified this record recently (last verified Apr 2019), so the status shown — last known as Not yet recruiting — may be out of date.

Study summary

Hydronephrosis describes a condition of urine-filled dilation of the collecting system. Normally, urine flows through the urinary tract with minimal or low pressure. If the build-up of excess fluid in the urinary collecting system continues, there will be an increase in pressure and atrophy of renal cortex. If hydronephrosis is left untreated for a long time, renal damage with permanent loss of function occurs

Study population

Patients will be recruited from out-patient clinics and in-patient sectors of Assiut Urology and Nephrology hospital

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

    1. Patients for whom a percutaneous nephrostomy is indicated provided that the hydronephrosis is advanced ( parenchymal thickness not more than 5 mm ) 2) Patients for whom a nephrectomy is planned for a seemingly poorly functioning kidney along with either

Exclusion criteria

Exclusion Criteria:

  1. Target kidney is the only functioning or better functioning kidney or otherwise substantially contributing to the total renal function, so nephrectomy is not likely.
  2. Emergency cases where the general condition of the patient cannot withstand the logistics of undergoing a radioisotope study eg
  3. in the target kidney
  4. Patients unlikely to undergo a nephrectomy
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Groups and cohorts

  • Study group

    Patients will be recruited from out-patient clinics and in-patient sectors of Assiut Urology and Nephrology hospital

    Procedure: percutaneous nephrostomy

Interventions

  • Procedurepercutaneous nephrostomy

    The percutaneous nephrostomy will be done under sonographic or fluoroscopic guidance. Establishment of intravenous access and antibiotics will be performed half an hour prior to procedure particularly in patients presenting with urinary tract infection. The procedure will be done under local anesthesia but general anesthesia may be used for uncooperative patients. percutaneous nephrostomy will be performed in the prone position, however, in case of relative contraindication to prone position

06

What researchers measure

Primary outcomes

  1. The rate of increase in glomerular filtration rate after intervention

    the radioisotope measurement of glomerular filtration rate will be done before and after insertion of percutaneous nephrostomy tube

    Time frame: 3 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 16, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
