They are nearly always reported to occur in the urinary bladder, and the occurrence in less capacious renal pelvis is unusual. We report a solitary, typical jackstone in the renal pelvis without significant outflow obstruction that was successfully treated with retrograde intrarenal surgery followed by extracorporeal shockwave lithotripsy. This highlights the complex pathophysiological mechanisms in stone formation which needs to be further studied. It is important to recognize the characteristic shape of the renal calculi on the radiological investigation in the diagnosis of the jackstones.<\/jats:p>","DOI":"10.1155\/2021\/8816547","type":"journal-article","created":{"date-parts":[[2021,1,17]],"date-time":"2021-01-17T02:05:05Z","timestamp":1610849105000},"page":"1-3","source":"Crossref","is-referenced-by-count":9,"title":["Jackstone in the Kidney: An Unusual Calculus"],"prefix":"10.1155","volume":"2021","author":[{"given":"Serozsha","family":"Goonewardena","sequence":"first","affiliation":[{"name":"Department of Urology, National Hospital of Sri Lanka, Colombo, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0398-5197","authenticated-orcid":true,"given":"Umesh","family":"Jayarajah","sequence":"additional","affiliation":[{"name":"Department of Urology, National Hospital of Sri Lanka, Colombo, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanka Nalinda","family":"Kuruppu","sequence":"additional","affiliation":[{"name":"Department of Urology, National Hospital of Sri Lanka, Colombo, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manoj Hilary","family":"Fernando","sequence":"additional","affiliation":[{"name":"Department of Urology, National Hospital of Sri Lanka, Colombo, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1186\/s12894-017-0230-6"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.4103\/0970-1591.91449"},{"key":"3","first-page":"507","article-title":"The microscopic structure of urinary calculi of oxalate of lime, with special reference to the spiculated variety","volume":"13","author":"H.
