Management of calyceal diverticular stones with extracorporeal shock wave lithotripsy and percutaneous nephrolithotomy: long-term outcome.Turna B, Raza A, Moussa S, Smith G, Tolley DA Department of Urology and Scottish Lithotriptor Centre, Western General Hospital, Edinburgh, UK. burakturna@gmail.com OBJECTIVE: To review patients with an extended follow-up after extracorporeal shock wave lithotripsy (ESWL) or percutaneous nephrolithotomy (PCNL) for calyceal diverticular stones (CDS), over a 15-year period, assessing the long-term outcome. PATIENTS AND METHODS: In all, 56 patients were treated for symptomatic CDS disease by ESWL (38) or PCNL (18). The stone-bearing diverticula were in the upper calyces in 26, middle calyces in 24 and lower calyces in six patients, and in the right kidney in 22 and in the left in 34. The most frequent symptom was ipsilateral flank pain (84%) and 32% of patients presented with associated chronic urinary tract infections. In a retrospective analysis, we assessed stone size, diverticulum location, stone-free rate, symptom-free rate, complications and extended follow-up. RESULTS: In the short-term in the ESWL group, 21% of patients were stone-free and 61% were asymptomatic; 8% developed symptoms and 8% developed recurrence or stone-growth in the long term. There were six minor complications. In the PCNL group, 15 patients (83%) were stone-free in the short term; two had a recurrence (11%) and two had stone growth (11) in the long term. There were three complications after PCNL. CONCLUSIONS: This series shows that PCNL is an effective and durable means of treating CDS, regardless of stone size or location of the diverticulum. Despite low stone-free rates with ESWL, most patients were rendered symptom-free with minimal complications. The long-term recurrence rates, 8% for ESWL and 11% for PCNL, were comparable.
