preoperative evaluation of erectile function with dynamic infusion cavernosometry Cavernosography in patients undergoing surgery for peyronie s disease correlation with postoperative results
The Journal of Urology, 1993Co-Authors: Gerald H Jordan, Kenneth W AngermeierAbstract:Most reports of surgical therapy for Peyronie's disease to date have not included detailed preoperative assessment of erectile function. To evaluate the relationship between preoperative erectile function and postoperative success, we reviewed 25 consecutive patients with Peyronie's disease who underwent surgery and evaluation with dynamic infusion cavernosometry and Cavernosography preoperatively. Overall results of dynamic infusion cavernosometry and Cavernosography revealed corporeal veno-occlusive dysfunction in 76% of the patients and inadequate arterial inflow parameters in 44%. Among 20 patients treated with plaque excision and dermal graft inlay, adequate postoperative erectile function for satisfactory intercourse occurred in 4 of 4 (100%) with an equilibrium accumulated intracorporeal pressure of greater than or equal to 70 mm. Hg, 9 of 12 (75%) with an equilibrium accumulated intracorporeal pressure of 40 to 65 mm. Hg and 1 of 4 (25%) with an equilibrium accumulated intracorporeal pressure of less than 35 mm. Hg. These data may be helpful to counsel patients before surgical therapy, and may explain some of the disparate results previously reported after plaque excision and dermal graft inlay on the basis of patient selection.

evaluation of erectile dysfunction by dynamic infusion cavernosometry and Cavernosography dicc multi institutional study
Urology, 1993Co-Authors: Joel M Kaufman, Fernando D Borges, William P Fitch, Reuven A Geller, Michael B Gruber, John G Hubbard, Donald L Mckay, John P Tuttle, Frederick R WittenAbstract:Abstract In a cooperative, private practice, multi-institutional impotence study, dynamic infusion cavernosometry and Cavernosography (DICC) was performed on 743 patients to make an accurate diagnosis and/or identify candidates for penile revascularization. Maximum equilibrium intracorporeal pressure achieved following papaverine and phentolamine injection (Phase 1) averaged 29.42 t 0.76 mm Hg, approximately one third of normal erection pressure. Corporeal pressure fall from 150 mm Hg over thirty seconds (cavernosometry) averaged 82.38 ± 1.33 mm Hg (Phase II). The gradient between systolic and cavernosal artery pressure averaged 42.84 ± 1.12 mm Hg on the right and 43.33 ± 1.13 mm Hg on the left (Phase III). Cavernosography at 90 mm Hg erection pressure was performed in Phase IV. Of the 124 patients from one center who were reviewed in greater detail, pure cavernosal artery insufficiency (CAI) was found in 25 (20.2 %), corporeal veno-occlusive dysfunction (CVOD) in 26 (21.0 %), and 73 patients (58.9 %) demonstrated combined CAI and CVOD. Diabetics (n = 69) achieved lower equilibrium intracorporeal pressures than nondiabetics, had similar CVOD, and worse CAI. Smokers (n = 365) and patients with Peyronie's disease (n = 32) had erectile dysfunction similar to those without these conditions. Patients impotent after trauma (n = 124) were younger, achieved higher intracorporeal pressures, and showed better corporeal veno-occlusive function than those without trauma. Complications of DICC were minimal and infrequent. After DICC, 169 patients underwent internal pudendal arteriography, 105 had arterial bypass surgery with or without penile venous ligation procedures, and 45 had venous surgery alone. Dynamic infusion cavernosometry and Cavernosography is a useful erectile function study to evaluate impotence and can be performed easily in a private practice setting.

Urethrography and Cavernosography Imaging in a Small Series of Penile Fractures: A Comparison With Surgical Findings
Urology, 1998Co-Authors: Jack H. Mydlo, Michael Hayyeri, Richard J. MacchiaAbstract:Abstract Objectives. To compare our results of preoperative corporal Cavernosography and retrograde urethrography in penile fractures with the clinical and intraoperative findings. Methods. From January to October 1996, 7 cases of penile fracture were diagnosed at our inner city trauma center. All cases were associated with sexual activity and patients underwent preoperative retrograde urethrography and corpus Cavernosography with immediate surgical intervention. Results. We found that 2 patients who presented with blood at the meatus had intact urethras, whereas 2 of the 3 patients who had urethral lacerations did not have a bloody meatus. In 2 cases the urethrogram and cavernosogram revealed lacerations that were not initially detected surgically. However, in another 2 cases, the urethrogram and cavernosogram were falsely negative. Two of the seven corporal fractures were bilateral and five were unilateral. Conclusions. On the basis of this small sample, it appears that preoperative Cavernosography and retrograde urethrography may show additional sites of tears in the corpora and urethra because hematoma formation may mask some ruptures. However, the presence or absence of a bloody meatus may not necessarily correlate with the status of the urethra, and the urologist also should be wary of a false-negative imaging study. We suggest that all cases of penile fracture be explored surgically, but preferably by a subcoronal degloving incision that allows careful examination of the urethra and corpora. Results of a larger series may determine if the routine use of these imaging modalities is justified intraoperatively.
