Objectives:

Percutaneous cystolithotomy (PCCL) is a minimally invasive procedure used for removal of urethral and bladder uroliths in dogs and cats. Poor information is available about the effectiveness of this technique for the resolution of complicated urethral obstruction (UO) that might need intraoperative retro-urohydropulsion. The aim of this study was to compare the use of PCCL as elective surgery and in case of complicated UO.

Methods:

Dogs and cats submitted to PCCL surgery from March, 2017 to October, 2023 were retrospectively included and divided in three groups:

1) Elective surgery

2) UO with preoperative retro-urohydropulsion

3) Complicated UO with intraoperative resolution of obstruction

Differences between groups were evaluated with parametric statistics, considering significative a p value <0.05.

Results:

Eighty patients (sixty-two dogs and eighteen cats) were included and divided in the three groups:

1) 30/80 (37.5%)

2) 31/80 (38.7%)

3) 19/80 (23.8%)

Median surgical time was 100 minutes (range 18-272); there was no statistical difference between the three groups regardless of length of surgery, perioperative complications, and duration of hospitalization. Complete uroliths removal was achieved in 80/80 (100%) cases and all complicated UO of group 3 were endoscopically resolved during PCCL without complications. One or more concomitant surgical procedures were performed in 40/80 (50%) cases and in 4/80 (5%) conversion to open-surgery was necessary. A number of uroliths <5 was statistically associated to a shorter surgical time (p=0.01).

Conclusions:

PCCL represents an effective minimally invasive technique useful also in complicated UO without a significative increase in surgical time or perioperative complications.
