Bladder Catheterization After Mini-PCNL

Single-center Randomized Study Evaluating Feasibility of Routine Bladder Catheterization After Mini- Percutaneous Nephrolithotripsy (PCNL)

60 patients

Inclusion Criteria:

• age from 18 to 70 years
• Indications for mini-PCNL
• ASA score: 1-3
• Single percutaneous access to pyelocaliceal system
• Size of solitary calculus up to 2.5 cm

Exclusion Criteria:

• Active urinary tract infection
• Coagulopathy
• Clinically significant infravesical obstruction (Qmax less than 10 ml / s, PVR more than 50 ml)

60 patients after PCNL will be recruited and randomized into 2 groups (30 vs 30):

• No Catheterization after mini-PCNL (study) - the bladder catheterization is not performed.
• Catheterization after mini-PCNL (control) - the bladder will be drained with the urethral catheter.

All patients will fill out the VASP in 2, 6, 12, 24 hours after mini-PCNL. Ultrasound examination of urinary bladder will be performed after mini-PCNL. All the AE will be registered.
