---|---|
Study details | |
Study aim | Description of primary and secondary aims of the study |
Study setting | Hospital setting and volume of cases performed each year |
Study design | Retrospective (clinical audit), prospective (comparative) study (non-randomised), randomised controlled trial |
Selection criteria | Description of how patients were enrolled e.g. consecutively |
Inclusion criteria | |
Exclusion criteria | |
Indication for surgery | |
Pre-operative | |
Operating team | Number of surgeons performing surgery |
Surgical team and subspecialty | |
Experience of surgeon e.g. case volume in year or career | |
State whether resident involvement | |
Patient information | Breakdown demographics and later results by age group: |
e.g. infants/children/pre-puberty/adolescence | |
Weight (can also be used to breakdown sample) | |
Previous treatments undergone by patient during that stone episode | |
Comorbidity | |
Pre-operative urine culture | |
Medical therapy | Specify if any patients had MET (either pre or post-operatively) |
Pharmacotherapy for stone disease (e.g. cystinuria) | |
Imaging | Breakdown of imaging modalities used |
Pre-operative stone status | Stone size |
Stone volume (include formula for calculation) | |
Stone density (Hounsfield units) | |
Stone location (both in kidney and ureter) | |
Pre-operative stone obstruction (hydronephrosis/proximal dilatation) | |
Pre-stenting | Indicate if planned pre-operative stenting was performed |
If pre-stented — indicate if this procedure included in complications and total number procedures patients went through to calculate SFR | |
Proportion of patients with indwelling nephrostomy | |
Operative | |
Timing | Breakdown of elective and emergency cases |
Operative time | |
Anaesthesia | |
Equipment and description of URS procedure | Patient positioning |
Type and dimensions of ureteroscope(s) | |
Energy source for lithotripsy | |
Laser type and power output | |
Start-up settings | |
Extras: Laser activation time, total laser energy | |
Fragmentation strategy: basketing or dusting or both | |
Use of access sheath (including size) | |
Radiation exposure | Use of radiation protection measures e.g. patient shield |
Fluoroscopy time | |
Effective dose (mSv) | |
Access success | % success at accessing upper urinary tract at the initial surgery |
If active dilatation (e.g. balloon) performed provide details of settings used | |
Complications | Report any intra operative complications and status of ureter on exit |
Use a validated grading tool wherever possible | |
Exit strategy | Breakdown of patients receiving stent, ureteral catheter or nephrostomy (new or left in situ) |
Specify if stent modification used e.g. Stent on string | |
Duration of indwelling stent (or other) | |
State whether check URS performed at time of stent removal | |
Number of patients with indwelling urethral catheter and duration | |
Post-operative | |
Follow-up | Timing when follow-up performed |
Stone composition (if available) | |
SFR | Definition and imaging used to calculate SFR |
Include zero-fragment definition | |
Breakdown of SFR according to ureteral and renal stones rather than pooled result only | |
Give initial SFR after first procedure as well as final SFR after any additional URS treatments required | |
Provide total and average number of URS procedures each patient required to become stone-free | |
Auxiliary treatment | Give details on any further intervention e.g. PCNL required to become stone-free and provide a further SFR result including this accordingly |
Complications | Use a validated grading tool wherever possible |
Specify if complications were per patient, procedure or renal unit | |
Include complications occurring during all stages of stone treatment i.e. pre-stenting, formal stone surgery, post-operative and stent removal | |
Indicate if complication rate is for URS procedure only or whether it includes additional procedures such as stent removal |
