DUOLITH® SD1 T-TOP »ultra« – The New Focused Shock Wave Generation

High-quality workmanship and optimal ergonomics mark the design of the new focused shock wave generation with the SEPIA® handpiece. The special flexibility of the handpiece cable supports effortless and, thus, easier treatment always directly at the patient – an important factor in the day-to-day work.

The SEPIA® handpiece renders the treatment with focused shock waves easy and efficient. All the important control elements have been integrated into the handpiece. Frequency and energy level can be adjusted directly at the handpiece.

An advantage for users: The SEPIA® handpiece is compatible with all DUOLITH® SD1 »ultra« systems available. Users benefit from reduced revision costs thanks to the easy change of the coil.


  • Effective and effortless treatment directly at the patient
  • All control elements integrated into the handpiece
  • Reduced revision costs thanks to easy change of coil
  • Focal zone depth: 0 – 65 mm
  • Therapeutic effectiveness: up to 125 mm penetration depth
  • Upgradable to DUOLITH® SD1 TOWER »ultra« by modular extensions

DUOLITH® SD1 T-TOP »ultra«: shock wave treatment for erectile dysfunction (ED)* and urological pain therapy

The DUOLITH® SD1 T-TOP »ultra« is a shock wave therapy system for the treatment of erectile dysfunction (ED) of vascular origin, induratio penis plastica (IPP) and chronic pelvic pain syndrome (CPPS). Scientific studies have proven the efficacy of focused shock waves for these indications. Click the Learn More button for references.

The effectiveness of the DUOLITH® SD1 T-TOP »ultra« is determined by the individually selectable, high dynamic and optimal energy range and the adjustable therapeutic depth of focus. Deep-lying areas can be treated easily. With its optimal focus zone, it is easy to access these areas with a high degree of accuracy. These technical features also demonstrate the superiority of the treatment. Due to the depth of focus, shock waves only can be applied from one side of the penis during treatment. Another highlight is the focused handpiece SEPIA® with its anatomically shaped stand-off for a perfect adaptation to the anatomy of the penis (for treatment of ED or IPP).

Induratio penis plastica (IPP) treatment with shock waves

Induratio penis plastica (IPP), also known as Peyronie’s disease, is an acquired and generally progressive condition of the penis. Most men notice the presence of the disease when they feel thickened nodules (so-called plaques) under the skin of the penis. As the disease progresses, pain may occur with or without an erection and the penis becomes curved during an erection, which can make it difficult or impossible to have sexual intercourse.

When treating IPP/Peyronie’s disease, the pain points in the penis are treated with extracorporeal shock waves. In a pilot study , shock waves were delivered to the nonerect penis once a week for a period of five weeks. 18 months after the last shock wave session, the deviation angle had decreased from 59.3° ± 38.1° to 49.3° ± 32.5° (N = 24; P = 0.1496). Pain during erection disappeared in 15 of 17 patients and was reduced in one other patient (P < 0.0001). After shock wave treatment,
15 patients achieved satisfactory sexual intercourse (before treatment: six patients). In 2009, a clinical trial with 100 patients concluded that ESWT leads to resolution of pain and improves both erectile function and quality of life. At 12-week follow-up, mean VAS score, mean IIEF-5 score, and mean QoL score improved significantly in patients receiving shock wave therapy. After 24 weeks, mean IIEF-5 score and mean QoL score were stable in the shock wave group, while the mean VAS score decreased even further. »Interestingly, after 24 wk, mean plaque size and mean curvature degree were significantly higher in the placebo group when compared with both baseline and ESWT values«. The authors of a systematic review published in 2017 also came to the conclusion that ESWT may resolve pain in patients with IPP/Peyronie’s disease.
