Outcome Measures

Primary Outcomes (1)

  • Total number of complications

    Any of: Emergency department visits related to procedure, unplanned provider visits, re-admission related to the procedure, blood transfusion, and need for secondary procedures. Patients with an emergency department or provider visit leading to re-admission will be classified once in the primary outcome as re-admission.

    4 weeks after surgery

Secondary Outcomes (5)

  • Stone free status

    4 weeks after surgery

  • Change in Wisconsin Stone Quality of Life Questionnaire by 10 points or more from baseline to 4 weeks after surgery.

    This will be completed at the initial visit (baseline) and at the follow-up visit 4 weeks later.

  • Cumulative opiate morphine equivalent dosing

    4 weeks after surgery

  • Return to work

    4 weeks after surgery

  • Time in hospital

    1 week after surgery

Study Arms (2)

Ambulatory tubeless PCNL

ACTIVE COMPARATOR

Patients will be discharged home on the same day as surgery. No nephrostomy tube will be placed (tubeless).

Procedure: Ambulatory tubeless PCNL

Inpatient PCNL with nephrostomy tube

ACTIVE COMPARATOR

Patients will be admitted to hospital for 1-3 days with a nephrostomy tube placed at the time of surgery that will then be removed prior to discharge.

Procedure: Inpatient PCNL with nephrostomy tube

Interventions

Patients will be discharged the same day of surgery. No nephrostomy tube will be left in place. A ureteral stent on a string may be left for up to 5 days.

Ambulatory tubeless PCNL

Patients will be admitted to hospital for 1-3 days. A nephrostomy tube will be placed at the time of surgery that will be removed prior to discharge.

Inpatient PCNL with nephrostomy tube
