Summary
# Editorial Summary: Long-term Management of Sabulous Cystitis in Five Horses Sabulous cystitis—characterised by sand or mineral accumulation within the bladder—presents a significant clinical challenge in equine practice, yet long-term management strategies remain poorly documented. Rendle and colleagues followed five horses over a three-year period, employing cystoscopic-guided saline lavage combined with catheter evacuation of the bladder to remove sabulous material, alongside antimicrobial therapy, anti-inflammatory medication, and bethanechol chloride (a cholinergic agent to enhance bladder contractility). Four of the five horses successfully returned to work; however, the fifth developed persistent incontinence requiring retirement, whilst one animal treated with frequent catheterisation alone subsequently developed a urethral stricture as a complication. These findings suggest that whilst aggressive mechanical removal of sabulous deposits offers reasonable prognosis for return to function, the choice between regular cystoscopic intervention and repeated catheterisation warrants careful consideration given the potential for iatrogenic urethral damage, and practitioners should counsel owners that some cases may remain refractory to current management protocols.

Practical Takeaways
- •Sabulous cystitis can be managed long-term with a combination of mechanical removal (catheterization and lavage), antimicrobial therapy, anti-inflammatory medication, and bethanechol chloride, allowing return to work in most cases
- •Cystoscopic guidance during saline lavage is preferable to frequent blind catheterization, as repeated catheterization carries risk of iatrogenic urethral stricture formation
- •Treatment success is variable; while 80% of cases returned to work, clinicians should counsel clients on realistic outcomes and the need for prolonged management protocols
Key Findings
- •Four of five horses with sabulous cystitis returned to work following combined treatment with catheterization, saline lavage, antimicrobial therapy, and bethanechol chloride over up to three years
- •Cystoscopic-guided saline lavage effectively removed residual sabulous material from the bladder
- •Frequent catheterization as an alternative to regular cystoscopy resulted in development of urethral stricture in one horse
- •One horse was retired due to persistent incontinence despite treatment
