This anomaly is in a continuum of duplex collecting systems and most commonly involves a common distal ureter. This is usually asymptomatic and is predominantly an incidental diagnosis, nevertheless, is a potential risk factor for urolithiasis formation. Current surgical management of larger staghorn calculi favours percutaneous nephrolithotomy (PCNL) over traditional open surgery, however for multiple calculi and complex anatomy PCNL would require multiple punctures, with increased risk of bleeding, pleural injury, sepsis and ultimately failed stone clearance. We describe the case of a 71-year-old female with multiple calculi in bifid anatomy. A single open approach, aided with cold-ischaemia was successfully utilized in this context.<\/jats:p>","DOI":"10.1093\/jscr\/rjac547","type":"journal-article","created":{"date-parts":[[2022,11,27]],"date-time":"2022-11-27T22:19:24Z","timestamp":1669587564000},"source":"Crossref","is-referenced-by-count":0,"title":["Anatrophic nephrolithotomy and pyelolithotomy for dual staghorn calculi in bifid collecting system"],"prefix":"10.1093","volume":"2022","author":[{"given":"Isaac","family":"Ealing","sequence":"first","affiliation":[{"name":"Urology Department, Royal Prince Alfred Hospital , Sydney, New South Wales 2050 , Australia"},{"name":"Faculty of Medicine and Health, The University of Sydney , Sydney, New South Wales 2006 , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ross","family":"Calopedos","sequence":"additional","affiliation":[{"name":"Urology Department, Royal Prince Alfred Hospital , Sydney, New South Wales 2050 , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marnique","family":"Basto","sequence":"additional","affiliation":[{"name":"Urology Department, Royal Prince Alfred Hospital , Sydney, New South Wales 2050 , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catalina","family":"Palma","sequence":"additional","affiliation":[{"name":"Urology Department, Royal Prince Alfred Hospital , Sydney, New South Wales 2050 , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Boulas","sequence":"additional","affiliation":[{"name":"Urology Department, Royal Prince Alfred Hospital , Sydney, New South Wales 2050 , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2022,11,26]]},"reference":[{"key":"2022112722191584000_ref1","doi-asserted-by":"crossref","first-page":"3005","DOI":"10.16965\/ijar.2016.393","article-title":"A study of human cadaveric ureter by simple dissection method","volume":"4","author":"Deka","year":"2016","journal-title":"Int J Anat Res"},{"key":"2022112722191584000_ref2","doi-asserted-by":"crossref","first-page":"2358","DOI":"10.18203\/2320-6012.ijrms20172094","article-title":"A cadaveric study on anatomical variations of kidney and ureter in India","volume":"5","author":"Choudhary","year":"2017","journal-title":"Int J Res Med Sci"},{"key":"2022112722191584000_ref3","first-page":"e7760e","article-title":"Double ureter: incidence, types, and its applied significance: a cadaveric study","volume":"12","author":"Arumugam","year":"2020","journal-title":"Cureus"},{"key":"2022112722191584000_ref4","doi-asserted-by":"crossref","DOI":"10.1097\/MD.0000000000011474","article-title":"Obstruction of bifid ureter by two calculi: a case report","volume":"97","author":"Xiao","year":"2018","journal-title":"Medicine"},{"key":"2022112722191584000_ref5","doi-asserted-by":"crossref","first-page":"e23","DOI":"10.1016\/j.urology.2016.10.003","article-title":"Ureteral stone in the distal blind-ending branch of a bifid ureter","volume":"99","author":"Niwa","year":"2017","journal-title":"Urology"},{"key":"2022112722191584000_ref6","doi-asserted-by":"crossref","first-page":"196","DOI":"10.4103\/UA.UA_142_19","article-title":"Combination of urolithiasis and anomaly: bifid ureter with fusion in the intramural part","volume":"12","author":"Protoshchak","year":"2020","journal-title":"Urol Ann"},{"key":"2022112722191584000_ref7","doi-asserted-by":"crossref","first-page":"515","DOI":"10.2214\/ajr.151.3.515","article-title":"Treatment of ureteropelvic strictures with percutaneous pyelotomy: experience in 62 patients","volume":"151","author":"Lee","year":"1988","journal-title":"AJR Am J Roentgenol"},{"key":"2022112722191584000_ref8","doi-asserted-by":"crossref","first-page":"218","DOI":"10.1016\/0090-4295(95)80008-5","article-title":"Current indications for open stone surgery in an endourology center","volume":"45","author":"Kane","year":"1995","journal-title":"Urology"},{"key":"2022112722191584000_ref9","doi-asserted-by":"crossref","first-page":"426","DOI":"10.1080\/003655902762467576","article-title":"Modified anatrophic nephrolithotomy for complete staghorn calculus disease -- does it still have a place?","volume":"36","author":"Melissourgos","year":"2002","journal-title":"Scand J Urol Nephrol"},{"key":"2022112722191584000_ref10","first-page":"Pc01","article-title":"Anatrophic nephrolithotomy in the management of large staghorn calculi -
