Background: Electrohydraulic lithotripsy (EHL) has been used as an alternative to cystotomy in human medicine to remove urinary calculi. This prospective study evaluated the efficacy and safety of EHL to remove urinary calculi in dogs.Hypothesis: EHL is an efficient and safe method of treatment of bladder and urethral calculi in dogs. Methods: Dogs presented between January 1, 2005 and June 1, 2007 with lower urinary tract calculi diagnosed by radiographs or ultrasound examination were included in the study. Physical examination, CBC, biochemistry, urinalysis, and urine culture were performed at presentation. EHL and voiding urohydropulsion were performed under general anesthesia. Patients received IV fluids for 12 hours after which they were rechecked by ultrasound examination and discharged with antibiotics and anti-inflammatory drugs for 5 days. All patients were reevaluated 1, 3, and 6 months after presentation by physical examination, urinalysis, and ultrasonography.Results: Twenty-eight dogs (19 males, 9 females) presented with bladder or urethral calculi or both underwent lithotripsy. Their median weight was 8.3 kg. Calcium oxalate calculi were present in 22 dogs, struvite in 4, and mixed calculi in 2. Fragmentation was done in the bladder (23 dogs) and in the urethra (12 dogs). Calculus-free rate was higher for urethral than for bladder calculi in males and higher for bladder calculi in females than in males. No major complications were reported. Twelve dogs relapsed within 6 months.Conclusions: Results of this study support the use of EHL as a minimally invasive treatment for bladder calculi in females and for urethral calculi in male dogs.

“…Bei großen Steinen ist die vorherige instrumentelle Lithotripsie und/ oder eine dorsomediane Sphincterotomie notwendig (Laverty et al 1992, Mair und Holt 1994, Eustace et al 1988. Postoperativ kann in wenigen Fällen Harninkontinenz auftreten (Laverty et al 1992).…”

“…Neben der manuellen Fragmentierung großer Urolithen mittels verschiedener Zangen oder eines Stößels ist hierzu der Einsatz verschiedener, aus der Humanmedizin übernommener, medizinischer Laser (z. B. gepulster Farbstofflaser oder konstanter Holmium:Yttrium-AluminiumGarnet-Laser), eines elektrohydraulischen und eines ballistic shock wave Lithotriptors beschrieben (Howard et al 1998, Koenig et al 1999, Judy und Galuppo 2002, May et al 2001, Simhofer und Riedelberger 2002, Eustace et al 1988, Plocki et al 1993). …”

Zusammenfassung:Anhand eines Falles von Urolithiasis bei einem Wallach wird der Komplex dieser Erkrankung bei Equiden und dessen Diskussion in der Literatur erörtert. Urolithiasis in the horseBased on a case of cystic calculus in a gelding the complex of equine urolithiasis is reviewed in this article. Despite the predisposing factors of the physiology of the equine urinary tract, e.g. alkaline pH-value of the urine, physiological calcium-supersaturation, the prevalence is low. Concerning the whole population and it is only 0,11%. The aetiology of this disease is not well known yet. One possible explanation for the development of urinary calculi could be imbalances of the substances that inhibit or promote initial crystal growth, but this theory has not been well investigated yet. The clinical signs of urolithiasis vary and depend on localisation and degree of obstruction. Clinical findings are colic, micturition interferences, changes of the urine and/or blood parameter, locomotor disorder, changes in urination behaviour and loss of condition. Different surgical approaches and different methods of lithotripsy are presented; the choice of surgical procedure in this case, its performance and the results of follow-up examinations are described for this patient. The spectroscopic analysis and macroscopic classification of the urolith enables to draw conclusions considering the pathogenesis of stone formation and points out ways of prophylaxis. Special dietetic and pharmacological acidification are discussed in the literature for urolithiasis prevention. Both methods reveal the possibilities and limits of a prophylaxis management. The limited number of scientifically confirmed studies leaves questions concerning aetiology, dietetics and prophylaxis.

“…[1][2][3][4] Options for resolution of lower urinary tract urocystoliths, urethroliths, or both include surgical or minimally invasive removal. [5][6][7][8][9][10][11][12][13][14][15][16] Disadvantages of some surgical methods used to remove lower urinary tract uroliths include general anesthesia and the possibility of complications such as peritonitis and perforation of the bladder, urethra, or rectum.

Disadvantages of laser lithotripsy include the cost of the laser and endoscopic access to the bladder via perineal urethrotomy in males.…”

Background: Laser lithotripsy has been used as an alternative to surgical removal of uroliths. Objective: To describe the procedure and efficacy of laser lithotripsy for removal of lower urinary tract uroliths in horses. Additionally, the ultrastructure and the differences in mineralogy and microstructure from 1 successful and 1 unsuccessful laser lithotripsy case are described.Animals: Six client-owned horses with 7 episodes of naturally occurring urocystoliths, urethroliths, or both. Methods: Retrospective study of all horses treated between 2006 and 2008 by laser lithotripsy. All horses were sedated followed by laser lithotripsy. Quantitative urolith analysis was performed in all cases. Ultrastructure and microstructure analyses were performed on uroliths from 2 horses.Results: Procedural success was achieved in 5 of 7 laser lithotripsy procedures. No complications occurred as a result of laser lithotripsy. One horse developed uroabdomen likely as a result of manual lithotrite disruption of the bladder after failure of laser lithotripsy. There were differences in microstructure between 1 urolith that was successfully fragmented by laser lithotripsy and 1 urolith that was resistant to laser fragmentation.Conclusions and Clinical Importance: Laser lithotripsy is an effective procedure for removal of some urocystoliths, urethroliths, or both in horses.
