Among the primary concerns facing men diagnosed with localized prostate cancer, the fear of chronic urinary incontinence is paramount. The thought of relying on absorbent pads or experiencing involuntary leakage during daily activities can cause significant anxiety. While traditional radical prostatectomy historically carried higher risks of long-term urinary complications, advancements in robotic technology and specialized anatomical surgical techniques have altered recovery outcomes.
Achieving rapid post-operative urinary control depends on preserving delicate muscular structures, maintaining maximal urethral length, and strengthening the pelvic floor prior to surgery.
As Director of Men’s Health and Urologic Oncology at St. Francis Hospital & Heart Center in Roslyn, New York, Dr. David Samadi combines master-level surgical sphincter preservation with structured pelvic floor rehabilitation protocols. Backed by his strict “Samadi Guarantee”—personally performing 100% of every procedure—Dr. Samadi achieves a 97% long-term urinary continence rate, helping men across Long Island regain bladder control and return to normal life.
The Anatomy of Urinary Continence
To understand post-prostatectomy urinary control, it helps to review how the male urinary valve system operates:
[Bladder Neck (Internal Sphincter)] ──► Removed during prostate excision
│
▼
[External Urethral Sphincter (EUS)] ──► Primary voluntary muscle remaining
│
▼
[Pelvic Floor (Levator Ani Complex)]──► Structural support sling for the sphincter
- The Internal Sphincter (Bladder Neck): Located at the junction of the bladder and prostate, this involuntary valve is removed along with the prostate gland during surgery.
- The External Urethral Sphincter (EUS): Located directly below the apex of the prostate, this muscular ring becomes the primary valve responsible for holding urine post-operatively.
- The Supporting Pelvic Floor: Surrounding the EUS, the levator ani muscle complex acts as a structural sling, lifting the urethra and providing dynamic closure pressure during sudden abdominal stress (such as coughing, laughing, or heavy lifting).

Surgical Precision: The SMART Sphincter-Preservation Protocol
While post-operative physical therapy reinforces pelvic muscles, ultimate continent recovery depends heavily on preserving sphincter integrity during surgery. Dr. David Samadi’s proprietary SMART (Samadi Modified Advanced Robotic Technique) procedure minimizes trauma to the urinary valve mechanism through distinct anatomical modifications:
[SMART Surgical Pathway]
│
├─► Suture-Free Dorsal Vein Control ──► Spires sphincter from compression & thermal shock
│
├─► Endopelvic Fascia Preservation ──► Leaves natural pelvic support structures intact
│
└─► Maximal Urethral Length Sparing ──► Retains dynamic muscle length for tight valve closure
1. Suture-Free Dorsal Vein Complex (DVC) Control
Standard robotic procedures frequently place heavy structural sutures directly through the Dorsal Vein Complex (a blood vessel network sitting directly over the external sphincter). This tension can compress or shorten the underlying urinary valve. Dr. Samadi deploys a proprietary, clipless, suture-free DVC protocol that controls bleeding without placing mechanical stress on the sphincter.
2. Preserving the Endopelvic Fascia
Traditional techniques slice open the endopelvic fascia—the fibrous tissue sheet lining the pelvic floor—to expose the surgical field. The SMART protocol approaches the prostate from the “inside out,” leaving the endopelvic fascia and surrounding supportive ligaments intact to maintain natural anatomical support for the bladder and urethra.
3. Maximal Functional Urethral Length Sparing
Under 10x 3D high-definition robotic magnification, Dr. Samadi dissects the prostate apex with sub-millimeter precision, maximizing the length of the remaining urethral segment. Preserving maximal urethral length provides a broader surface area for sphincter closure, directly accelerating post-catheter continence recovery.
Pre- and Post-Operative Pelvic Floor Physical Therapy (PFPT)
In conjunction with refined surgical preservation, Dr. Samadi incorporates structured Pelvic Floor Physical Therapy (Kegel Protocols) to condition the urethral support muscles before and after surgery:
| Recovery Phase | Clinical Focus / Action | Primary Therapeutic Benefit |
| Pre-Habilitation (3–4 weeks prior) | Targeted Levator Ani isolation & biofeedback | Establishes motor muscle memory before catheter placement |
| Catheter Phase (Day 1 to 7) | Muscle rest & catheter maintenance | Allows tissue healing around the bladder-urethral junction |
| Early Post-Catheter (Month 1) | Sub-maximal fast-twitch pelvic contractions | Reduces initial stress leakage during standing or walking |
| Late Conditioning (Months 2–3) | Sustained endurance contractions & core integration | Restores full dynamic bladder control during strenuous activity |
Expected Continence Recovery Timeline
Temporary stress incontinence immediately following catheter removal is a normal, expected part of the healing process as local tissue swelling subsides. Dr. Samadi’s structured approach leads to a predictable recovery trajectory:
- Weeks 1 to 4: Initial light-to-moderate stress leakage, requiring thin protective pads. Rapid initial improvements occur as surgical inflammation resolves.
- Months 2 to 3: Over 90% of SMART patients experience significant improvements in control, transitioning to a single security pad or achieving full pad-free status during daily routines.
- Months 3 to 6: Long-term stabilization, with 97% of patients achieving complete, pad-free urinary control.
Conclusion
Fearing permanent urinary incontinence should not prevent you from seeking a definitive prostate cancer cure. Through the SMART procedure’s sphincter-preservation techniques paired with structured pelvic floor physical therapy, Dr. David Samadi provides men across Long Island and greater New York with complete tumor elimination alongside preserved quality of life.
