“…Liu et al [ 20 ] reported that the cost of ureteral stent removal for patients with extraction strings was lower (8.97 ± 3.07 vs. 455 ± 0 CNY; P < 0.05). In a study by Lynch et al, their department saved €23,790 during the 7-month study period due to the successful removal of 61 stents with extraction strings [ 12 , 21 ]. For this advantage, several studies have identified the use of a string for self-removal of stents after URS as a cost-saving measure [ 12 ].…”

Objective. To evaluate the current evidence on the effectiveness and safety of ureteric stent removal using strings compared to conventional methods. Materials and Methods. The electronic databases PubMed, Embase, China National Knowledge Infrastructure (CNKI), and the Cochrane Library were systematically searched up to March 2020. Two reviewers searched the literature, independently extracted the data, and evaluated the quality of the studies according to the inclusion and exclusion criteria. The data analysis was performed with the software program Review Manager 5.3. Results. Eleven studies with a total of 1809 patients were included in the analysis based on the inclusion criteria. Our meta-analysis showed that visual analogue scale (VAS) scores were significantly lower in the string group than in the conventional group (weighted mean difference (WMD) -2.63; 95% confidence interval (CI) -3.68, -1.58; P < 0.00001 ). In terms of stent dwell time, the string group had an advantage (WMD -9.53; 95% CI -14.20, -4.86; P < 0.0001 ). In addition, no significant differences in the occurrence of urinary tract infection (UTI) (odds ratio (OR) 1.03; 95% CI 0.62, 1.72; P = 0.92 ), emergency room visits (OR 0.99; 95% CI 0.59, 1.67; P = 0.97 ), or other complications ( P > 0.05 ) were observed between the two groups. Conclusion. Our findings suggest that an extraction string is an effective and safe method for the removal of ureteric stents. This method gives patients the benefits of reduced pain and shortened stent dwell time without increasing the risk of UTI. Nevertheless, these findings should be further confirmed through large-volume, well-designed prospective randomized controlled trials (RCTs).

SamenvattingDe stent-on-string is een dubbel-J-katheter die de patiënt zelf kan verwijderen, als alternatief voor verwijdering met behulp van cystoscopie. Het doel van dit onderzoek is het in kaart brengen van luxaties, verblijfstijd en klachtenpatroon bij zelfverwijdering. Hiertoe is bij 60 patiënten nagegaan hoe en wanneer de stent-on-string is verwijderd en hoe de stent verdragen is. 42 stents (70,0%) werden op de aangegeven dag verwijderd. 46 patiënten (76,7%) deden dit zelf; vijf patiënten (8,3%) lukte het niet. In twee gevallen (3,3%) was een cystoscopie noodzakelijk. Vijf patiënten (8,3%) vermeldden hevige klachten. Inclusie vond plaats in twee fasen, waarbij in fase 2 een evidente aanpassing werd gezien in geïncludeerde patiënten. Het gebruik van een stent-on-string leidt tot een vermindering van het aantal cystoscopieën, een beperkt aantal vroegtijdige luxaties en in de meeste gevallen ervaart de patiënt geen tot milde klachten. Ervaring met de techniek lijkt te leiden tot minder luxaties en meer zelfverwijderingen.
