Abstract: The aim of this systematic review is to provide an updated report on the efficacy and complications of sacral neuromodulation (SNM) and percutaneous tibial nerve stimulation (PTNS) in the treatment of chronic nonobstructive urinary retention (CNOUR), with a focus on the contemporary technique of SNM utilizing the percutaneous placement of tined leads. This systematic review was conducted with the use of PRISMA guidelines and registered with PROSPERO (CRD42020208052). A systematic literature search was conducted in Embase, PubMed, and Cochrane databases. Inclusion criteria include English language and human participants. Exclusion criteria include SNM studies involving less than 10 CNOUR patients, studies containing data obtained using open, surgical implantation of nontined leads, and studies that only reported the test phase success rate with no long-term efficacy data. The risk of bias assessment was conducted using the National Institutes of Health study quality assessment tool. A total of 16 papers studies were included (11 SNM and 5 PTNS) in this review. The success rate for SNM ranges between 42.5% and 100% (median = 79.2%) for the test stimulation phase and 65.5%-100% (median = 89.1%) in the long term. Most SNM studies reported revision and explantation rates of lesser than 20%. The success rate was much lower for PTNS, in the 50%-60% range and complications were minimal. SNM using the contemporary percutaneous tined lead implantation technique appears to be an effective treatment for CNOUR and is durable in the long term. Compared to SNM, PTNS appears less efficacious with less evidence supporting its use in CNOUR. Further prospective studies are required to define the role of PTNS in the treatment of CNOUR.
