Electrovaporization (also referred to as the VaporTrode procedure, transurethral electrovaporization of the prostate, or vaporization of the prostate) uses one of several commercially available devices to destroy obstructive prostate tissue.
The VaporTrode procedure is designed to reduce the bothersome obstructive symptoms caused by benign prostatic hyperplasia and to increase both peak and mean flow rates.
Narayan and associates (1997) compared the efficacy of the VaporTrode procedure with visual laser ablation of the prostate in 64 men with BPH.
However, five (1.1%) of those treated by TURP required hospital admission as compared to one (0.3%) of the men treated by the VaporTrode procedure.
Meade and McLoughlin (1996) also reported relatively few complications following the VaporTrode procedure based on their experiences with 51 subjects.
It is important to note that both Ekengrad and Hahn (1996) and Shokeir and colleagues (1997) observed evidence that at least some of the irrigation fluid used during the VaporTrode procedure was absorbed through the venous bed of the prostate.
Several studies have examined the risk of sexual dysfunction following the VaporTrode procedure.
Because the VaporTrode procedure is gaining popularity as a technique for ablating obstructive tissue, and because the procedure offers several potential advantages when compared to laser prostatectomy or TIJRP, urologic nurses are actively involved in managing patients who undergo this procedure.
The operative time required for the VaporTrode procedure was compared to that required for a traditional TURP but no statistically significant differences were found.
Following the VaporTrode procedure, all patients were transported to the postanesthesia care unit with an indwelling urinary catheter.
A review of the literature from 1995 to 1998 revealed only one article describing the nursing management of the patient undergoing the VaporTrode procedure (Churchill, 1997).
A serum creatinine should be obtained as a routine part of a BPH evaluation and this laboratory value can be compared with values following the VaporTrode procedure to determine if one or both ureters is obstructed by postoperative edema or bleeding.
