Predictive Factors of Rabbani et al for Recovery of Erectile Function After Radical Prostatectomy

Description

Rabbani et al identified risk factors associated with recovery of erectile function after a radical prostatectomy. The potential impact of surgery on erectile function is an important aspect of preoperative informed consent. While patients may have some loss of potency immediately after surgery, many will show improvement over time. The authors are from Memorial Sloan-Kettering Cancer Center, Repatriation General Hospital (Australia) and Methodist Hospital in Houston.

Parameters:

(1) age of the patient

(2) level of erectile function prior to surgery

(3) extent of neurovascular bundle preservation

Preoperative Prediction

Age in Years	Level of Erectile Function	Probability of Potency at 24 Months	Probability of Potency at 36 Months
<= 60 years	full erection	63	69
	full erection but recently diminished	48	54
	partial erection	35	40
> 60 and <= 65 years	full erection	44	49
	full erection but recently diminished	31	36
	partial erection	22	25
> 65 years	full erection	37	42
	full erection but recently diminished	26	30
	partial erection	18	21

from Table 5, page 1932.

Post-operative Prediction with Bilateral Nerve Sparing

Age in Years	Level of Erectile Function	Probability of Potency at 24 Months	Probability of Potency at 36 Months
<= 60 years	full erection	70	76
	full erection but recently diminished	53	59
	partial erection	43	49
> 60 and <= 65 years	full erection	49	55
	full erection but recently diminished	34	39
	partial erection	27	31
> 65 years	full erection	43	49
	full erection but recently diminished	30	35
	partial erection	23	27

from Table 6, page 1933.

Post-operative Prediction with Unilateral or Bilateral Neurovascular Bundle Damage

Age in Years	Level of Erectile Function	Probability of Potency at 24 Months	Probability of Potency at 36 Months

	partial erection	35	40
> 60 and <= 65 years	full erection	40	46
	full erection but recently diminished	28	32
	partial erection	21	25
> 65 years	full erection	35	41
	full erection but recently diminished	24	28
	partial erection	18	21

from Table 6, page 1933.

Post-operative Prediction with Unilateral Neurovascular Bundle Resection

Age in Years	Level of Erectile Function	Probability of Potency at 24 Months	Probability of Potency at 36 Months
<= 60 years	full erection	26	30
	full erection but recently diminished	17	20
	partial erection	13	15
> 60 and <= 65 years	full erection	15	18
	full erection but recently diminished	10	12
	partial erection	7.5	8.8
> 65 years	full erection	13	15
	full erection but recently diminished	8.5	10
	partial erection	6.3	7.5
