urpose: We investigated the effectiveness of intravesical botulinum toxin-A (BTX-A) injection therapy in patients with lower urinary tract dysfunction (LUTD) and upper urinary tract (UUT) deterioration and evaluated whether BTX-A injection ther apy could substitute for augmentation uretero-enterocystoplasty (AUEC). Methods: Data from a prospective, single-center cohort from 2017–2021 were analyzed. Patients were divided into 2 treat ment groups: AUEC and BTX-A (i.e., patients who declined AUEC). Bladder and UUT functions were assessed by comparing clinical information, urodynamic data, laboratory results, and imaging records. Results: In total, 121 patients were enrolled (BTX-A group: 41 patients; AUEC group: 80 patients). The BTX-A group showed a reduced maximum detrusor pressure and increases in the maximum bladder volume and bladder compliance (P<0.05). However, in follow-up evaluations, significantly smaller improvements (all P<0.05) in urodynamic parameters were found in the BTX-A group than in the AUEC group. Notably, there was no significant improvement in vesicoureteral reflux (VUR; P=0.66) or upper urinary tract dilatation (UUTD; P=0.75) in the BTX-A group, and no statistically significant difference in serum creatinine (Scr) levels or the estimated glomerular filtration rate (eGFR) was observed in the follow-up evaluations (all P>0.05). Both VUR and UUTD improved significantly in the AUEC group, and the Scr and eGFR levels significantly im proved after AUEC relative to baseline levels (P<0.05). The reduction in the Scr level was significantly lower in the BTX-A group than in the AUEC group during 0–15 months of follow-up (Scr reduction differences, -1.36; P<0.01). Conclusions: Although BTX-A injection therapy was effective for improving bladder function, BTX-A injections did not alle viate UUT deterioration in this study, particularly in patients with advanced-stage LUTD. Conversely, AUEC for LUTD has a well-established role in improving UUT function. Hence, BTX-A injection therapy should not replace AUEC to ameliorate UUT impairment and protect UUT function.
