Patients with grade 0\u20131 hydronephrosis, fever or pyonephrosis were excluded. No patient had any contraindication for either method of drainage. Stable patients (or patients stabilised by dialysis) were randomised (non\u2010blinded, block randomisation, sealed envelope method) into\n PCN<\/jats:styled-content>\n \u2010tube or bilateral\n JJ<\/jats:styled-content>\n \u2010stent groups (45 patients for each group). Initial urinary drainage was performed under general anaesthesia and fluoroscopic guidance. We used 4.8\u20136 F\n JJ<\/jats:styled-content>\n stents or 6\u20138 F\n PCN<\/jats:styled-content>\n tubes. The primary outcomes were the safety and efficacy of both groups for the recovery of renal functions. Both groups were compared for operative and imaging times, complications, and the period required for a return to normal serum creatinine levels. The secondary outcomes included the number of subsequent interventions needed for clearance of stones. Additional analysis was done for factors affecting outcome within each group.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n All presented patients completed the study with intention\u2010to\u2010treat analysis. There was no significant difference between the\n PCN<\/jats:styled-content>\n \u2010tube and\n JJ<\/jats:styled-content>\n \u2010stent groups for the operative and imaging times, period for return to a normal creatinine level and failure of insertion. There were significantly more complications in the\n PCN<\/jats:styled-content>\n \u2010tube group. The stone size (>2\u2009cm) was the only factor affecting the rates of mucosal complications, operative time and failure of insertion in the\n JJ<\/jats:styled-content>\n \u2010stent group. The degree of hydronephrosis significantly affected the operative time for\n PCN<\/jats:styled-content>\n \u2010tube insertion. Grade 2 hydronephrosis was associated with all cases of insertion failure in the\n PCN<\/jats:styled-content>\n \u2010tube group. The total number of subsequent interventions needed to clear stones was significantly higher in the\n PCN<\/jats:styled-content>\n \u2010tube group, especially in patients with bilateral stones destined for chemolytic dissolution (alkalinisation) or extracorporeal shockwave lithotripsy (\n ESWL<\/jats:styled-content>\n ).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n We recommend the use of\n JJ<\/jats:styled-content>\n stents for initial urinary drainage for stones that will be subsequently treated with chemolytic dissolution or\n ESWL<\/jats:styled-content>\n , as this will lower the total number of subsequent interventions needed to clear the stones. This is also true for stones destined for ureteroscopy (\n URS<\/jats:styled-content>\n ), as\n JJ<\/jats:styled-content>\n \u2010stent insertion will facilitate subsequent\n URS<\/jats:styled-content>\n due to previous ureteric stenting. Mild hydronephrosis will prolong the operative time for\n PCN<\/jats:styled-content>\n \u2010tube insertion and may increase the incidence of insertion failure. We recommend the use of\n PCN<\/jats:styled-content>\n tube if the stone size is >2\u2009cm, as there was a greater risk of possible iatrogenic ureteric injury during stenting with these larger ureteric stones in addition to prolongation of operative time with an increased incidence of failure.\n <\/jats:p>\n
