Pararectal cystotomy for urolith removal in nine horses.

This research was conducted to assess the outcome of using standing pararectal cystotomy for the removal of bladder stones in horses. The researchers reviewed case histories and found that the procedure was generally safe, well-tolerated, had few complications, and could be a cost-effective alternative to techniques requiring general anesthesia.

Methodology

• The researchers conducted a study through a case series involving nine horses that had bladder stones (cystic calculi).
• They reviewed the medical records of these horses from December 1998 to May 2007.
• Relevant information like the number of bladder stones, their size and type, the surgical technique used, protocols for sedation and pain management, and any complications during or after the surgery were all analyzed.

Results

• The bladder stones, with an average diameter of 6.37 cm, were successfully removed from the horses without needing to be broken down.
• Out of the nine horses, eight (89%) experienced no complications during the procedure.
• One horse (11%) developed persistent discharge from the perineal (area between anus and scrotum or vulva) incision, which delayed the healing process.
• Despite the absence of stones revealed by a follow-up cystoscopy (examination of the bladder with a thin tube), this horse showed recurring symptoms associated with cystitis (bladder inflammation).
• The problem related to the persistent discharge was resolved after the surgical incision was revised.

Conclusions

• The study found that standing pararectal cystotomy can be a safe method to remove bladder stones from horses.
• Horses were able to tolerate the procedure well and no significant complications were observed.
• The authors conclude that this technique could provide an economical advantage because it can be done under sedation, eliminating the need for more expensive general anesthesia.
