Ultrasound-Guided Percutaneous Peritoneal Dialysis Catheter Insertion for Urgent-Start Dialysis: Feasibility, Technical Success, Safety, and Clinical Outcomes at Assiut University Hospital

This prospective observational study evaluates the feasibility, technical success, safety, and clinical outcomes of ultrasound-guided percutaneous peritoneal dialysis (PD) catheter insertion for urgent-start dialysis in pediatric patients with acute kidney injury (AKI).

Acute kidney injury in children frequently requires prompt renal replacement therapy. While traditional surgical placement of peritoneal dialysis catheters often requires general anesthesia and an extended waiting period before use, percutaneous insertion under real-time ultrasound guidance using a modified Seldinger technique allows for bedside placement under local anesthesia and rapid initiation of dialysis.

The study includes 50 pediatric patients (ranging from neonates up to 18 years of age) admitted to Assiut University Hospitals who require urgent renal replacement therapy and are candidates for peritoneal dialysis. Participants undergo percutaneous catheter placement guided in real time by ultrasound, followed by the initiation of an urgent-start dialysis protocol. The primary focus is to determine the technical success of the insertion procedure, evaluate catheter function and short-term catheter survival, and record procedure-related complications such as bleeding, dialysate leakage, infection, and mechanical malfunction. Secondary objectives include assessing renal recovery, patient survival to hospital discharge, and the need for conversion to alternative dialysis modalities.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Study Population

Pediatric patients (neonates up to 18 years of age) diagnosed with acute kidney injury according to KDIGO or pRIFLE criteria admitted to Assiut University Hospitals, Assiut, Egypt. The population includes patients requiring urgent renal replacement therapy who are candidates for peritoneal dialysis due to hemodynamic instability, lack of adequate vascular access, or clinical preference.

Description

Inclusion Criteria:

  • Pediatric patients (neonates up to 18 years of age) diagnosed with acute kidney injury according to KDIGO or pRIFLE criteria.
  • Clinical indication for urgent renal replacement therapy with candidacy for peritoneal dialysis (due to hemodynamic instability, lack of vascular access, or physician preference).
  • Written informed consent provided by a parent or legal guardian.

Exclusion Criteria:

  • Recent major abdominal surgery, abdominal wall defects, or necrotizing enterocolitis.
  • Diaphragmatic hernia or ventriculoperitoneal (VP) shunt in situ.
  • Uncontrolled peritonitis or intra-abdominal sepsis of surgical origin.
  • Severe coagulopathy precluding safe percutaneous catheter insertion.
  • Refusal of informed consent or inability to comply with protocol follow-up.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Pediatric Urgent-Start Peritoneal Dialysis Cohort

Pediatric patients (neonates up to 18 years) diagnosed with acute kidney injury according to KDIGO/pRIFLE criteria who require urgent renal replacement therapy and are candidates for peritoneal dialysis (due to hemodynamic instability, lack of vascular access, or clinical preference). All participants undergo percutaneous peritoneal dialysis catheter placement under real-time ultrasound guidance using a modified Seldinger technique, followed by the initiation of urgent-start peritoneal dialysis. Outcomes assessed include procedural feasibility, technical success, catheter function, short-term catheter survival, and procedure-related complications.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Technical Success of Catheter Placement
Time Frame: 1 hour post-procedure

Technical success is defined as successful percutaneous placement of the peritoneal dialysis catheter into the peritoneal cavity under real-time ultrasound guidance with immediate functional inflow and outflow, confirmed by free instillation and drainage of fluid without leakage or obstruction.
1 hour post-procedure

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
