Approximately 35% of women have stress urinary incontinence (SUI), and although TVT is now perceived as the standard treatment, the SPARC is a very similar procedure and is thought to have fewer peri\u2010operative complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>PATIENTS AND METHODS<\/jats:title>\n                    <jats:p>Patients with clinical SUI were recruited from public and private urology\/urogynaecology clinics, and participated in the trial of TVT vs SPARC. The primary outcome was bladder perforation; secondary outcomes were blood loss, voiding difficulty, urgency, and cure of SUI symptoms. Sample size calculations, based on an estimated 2% perforation rate, showed that 290 patients would be needed to detect a clinically significant difference of 5%. Stratification was by previous incontinence surgery and the experience of the surgeon.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      There were 301 operations; the difference in bladder perforations was not statistically significant, at one\/147 TVT (0.7%), and three\/154 SPARC (1.9%), with the difference in rate of 0.013 (95% confidence interval (CI) \u2212\u200a0.01 to 0.04; odds ratio 2.89, 95% CI 0.30\u201328.21;\n                      <jats:italic>P<\/jats:italic>\n                      \u2003=\u20030.62), and nor were differences in estimated blood loss of &gt;100\u2003mL (TVT, 32\/147, 21.8%; SPARC 28\/154, 18.2%);\n                      <jats:italic>de novo<\/jats:italic>\n                      urgency (TVT 15\/37, 40.5%; SPARC 14\/33, 42.4%), objective cure (TVT 143\/147, 97.3%; SPARC 148\/152, 97.4%) or vaginal mesh erosion (TVT 7\/147, 4.8%; SPARC 16\/152, 10.5%).

There was no statistically significant difference between TVT and SPARC in blood loss, urgency or objective cure of SUI symptoms at 6\u2003weeks. However, SPARC was more difficult to adjust correctly, and a statistically significant number of patients required loosening of the tape in theatre (\n                      <jats:italic>P<\/jats:italic>\n                      \u2003=\u20030.002). TVT had a lower rate of vaginal erosion and a statistically significantly higher cure rate of subjective SUI symptoms than SPARC. Overall, voiding difficulty (loosening of the tape), urgency and vaginal mesh erosion were the most important clinical problems. This trial showed the importance of testing new devices which appear to be similar, but which might have relevant differences. There was no financial assistance for this study, and a long\u2010term follow up is planned.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/j.1464-410x.2006.06333.x","type":"journal-article","created":{"date-parts":[[2006,7,6]],"date-time":"2006-07-06T21:41:38Z","timestamp":1152222098000},"page":"367-376","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":85,"title":["A randomized controlled equivalence trial of short\u2010term complications and efficacy of tension\u2010free vaginal tape and suprapubic urethral support sling for treating stress incontinence"],"prefix":"10.1111","volume":"98","author":[{"given":"H.
