Summary
# Editorial Summary: Pararectal Cystotomy for Urolith Removal in Standing Horses Standing pararectal cystotomy proved an effective and well-tolerated approach for removing bladder calculi in nine horses over an eight-year period, with eight animals (89%) experiencing uncomplicated recoveries and stones of considerable size (mean 6.4 cm diameter, range 3–10 cm) extracted intact without requiring fragmentation. Of the nine cases reviewed, only one horse developed a complication—persistent drainage from the perineal incision requiring subsequent wound revision—although notably, this animal later experienced recurrent clinical signs consistent with cystitis despite cystoscopic confirmation of urolith removal. By enabling calculus extraction under standing sedation rather than general anaesthesia, this surgical approach eliminates the cardiovascular and recovery risks associated with recumbency whilst offering substantial cost savings, making it a practical option for equine practitioners managing cystic calculi. The safety profile and technical success of the procedure suggests it merits consideration as a first-line intervention, though the recurrence of cystitis symptoms in one case indicates the importance of thorough postoperative monitoring and investigation of underlying predisposing factors, particularly those related to urinary tract infection or metabolic imbalances. For farriers and other equine professionals working alongside veterinary surgeons, understanding this technique's advantages may help in counselling owners of affected horses regarding realistic treatment expectations and recovery timeframes.

Practical Takeaways
- •Pararectal cystotomy is a viable standing procedure for urolith removal in horses, potentially reducing costs and anesthetic risks compared to recumbent approaches
- •Large uroliths (up to 10 cm diameter) can be removed intact without fragmentation using this technique, though post-surgical cystitis signs may recur
- •Incisional complications were minor and resolved with wound revision; this should be considered a manageable procedure with good safety profile
Key Findings
- •Pararectal cystotomy successfully removed uroliths (mean diameter 6.37 cm) intact without fragmentation in 9 horses under standing sedation
- •8 of 9 horses (89%) experienced no complications; 1 horse (11%) developed persistent drainage requiring wound revision
- •Procedure was well tolerated with no serious intra- or postoperative complications encountered
- •Standing pararectal approach offers potential economic advantage over general anesthesia-requiring surgical techniques
