Prostate Cancer
Conditions
Brief summary
The goal of this retrospective, observational study is to preliminarily learn about the safety and efficacy of two-step radical prostatectomy in the treatment of low- to intermediate-risk prostate cancer patients with enlarged prostate and severe benign prostatic hyperplasia. The main questions it aims to answer are: 1. Whether two-step prostatectomy is safe enough to decrease the surgical difficulty of these patients? 2. Whether the oncologic control is promising?
Interventions
PROCEDURETwo-step Radical Prostatectomy
The first step was the enucleation of the hyperplastic adenoma, followed by the anterograde radical prostatectomy of residual tissue

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Biochemical Recurrence-free Survival | 5 years | Number of participants who are free of biochemical relapse after a specified duration of time. Biochemical recurrence is measured by PSA levels. Biochemical recurrence was defined as a measurable serum PSA concentration 0.2 ng/ml or greater. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Estimated blood loss | Intraoperative | Defined as all the blood loss counting during the surgery |
| Hospital stay | From date of surgery until the date of discharge, an average of 7 days | Defined as the time duration between the first day after surgery to the day of discharge |
| Continence ContinenceContinence Continence Continence Continence Continence Continence Continence Continence | 2 weeks, 1 months, 3 months, 6 months, 12 months after surgery | Evaluated with the use of pad per day. Using no more than 1 pad per day is defined as complete continence |
| Surgical time | Intraoperative | Defined as the time duration from the incision at the opening to the end of closing the incision |
| Erectile function | 6 months, 12 months and 24 months after surgery | Evaluated with International Index of Erectile Function-5 (IIEF-5).The IIEF-5 score is the sum of the ordinal responses to the 5 items. 22-25: No erectile dysfunction 17-21: Mild erectile dysfunction 12-16: Mild to moderate erectile dysfunction 8-11: Moderate erectile dysfunction 5-7: Severe erectile dysfunction |
| Positive surgical margin rate | Through study completion, an average of 5 year | Defined as the proportion of patients with positive surgical margin of the whole prostate and the margin between the hyperplastic adenoma and the residual gland evaluated by pathologists. The location of positive margin will be documented. |
| Complication | Through study completion, an average of 5 year | All the complications which was evaluated relevant to the surgery will be documented and graded by Clavien-Dindo grade system. |
| Lower urinary tract symptoms | 1 months, 3 months, 6 months, 12 months after surgery | Evaluated with International Prostatic Symptom Score (IPSS). 1-7: Mild 8-19:Moderate 20-35: Severe |
