What makes Goldman's Aquablation surgery special?

Even with identical equipment, Aquablation outcomes vary with how the resection range is set and which function-preservation strategy is used, so planning experience and the treatment system matter. A precise surgical plan must address both urinary symptom relief and preservation of ejaculatory function. With this in mind, Goldman Urology performs Aquablation surgery centered on precise surgical design rather than on the equipment alone. With over 600 cases since introducing the procedure early in Korea, we plan the resection area for each patient's prostate size and shape, combining real-time ultrasound with AI-based planning for millimeter-level precision. We also apply the Hood Sparing technique, which preserves the fine structures around the verumontanum involved in ejaculation, cutting the rate of retrograde ejaculation to ½ of the conventional rate. This approach, which weighs better urination and function preservation together, can help lower the chance of retrograde ejaculation. After surgery, a step-by-step follow-up program tracks urinary symptoms and functional preservation, and an overnight on-call system for inpatients keeps recovery well managed. What defines Aquablation at Goldman is a systematic process, from precise preoperative planning and function-preserving strategies to postoperative recovery care.

How do you choose a hospital that performs Aquablation surgery well?

When choosing a hospital for Aquablation, check not only that it has the equipment but also its actual surgical experience, whether its planning accounts for function preservation, and its post-surgery care. Because Aquablation sets the resection range with a robot and real-time ultrasound, outcomes depend on the medical team's experience and the hospital's care system. Consider these criteria together.- Care by a urology specialist, and a dedicated prostate clinic- Number of Aquablation cases and experience with very large prostates- Surgical planning based on real-time ultrasound, and a function-preserving surgical strategy- A follow-up system that checks both urinary improvement and sexual function after surgery (such as an overnight on-call system in the inpatient ward) With Aquablation, outcomes differ by how the resection range is set and which function-preserving strategy is used, even with the same equipment. Confirm that the medical team has enough clinical experience to plan the procedure precisely. For example, Goldman Urology designs the resection range to each patient's prostate structure, drawing on 600+ cases since adopting the procedure early in Korea. AI-based planning is combined with real-time ultrasound for millimeter-level resection, and the Hood Sparing technique protects the microstructures around the verumontanum involved in ejaculatory function. After surgery, a follow-up program (including an overnight on-call system in the inpatient ward) checks urinary improvement and functional preservation, managing recovery step by step toward more stable outcomes.

How much does Aquablation (robotic waterjet) surgery cost?

The cost of Aquablation (robotic waterjet) surgery varies with prostate size, extent of surgery, tests required, and whether hospitalization is needed. The course of care may also differ by the patient's health and treatment plan. Since every prostate is different, no single price applies, but expect approximately 9 to 11 million KRW. An accurate estimate follows a detailed prostate examination and consultation.

How long does robotic waterjet surgery (Aquablation) take?

Robotic waterjet surgery (Aquablation) takes only 7–15 minutes, so the burden on the patient is small. Same-day discharge is possible, and many patients are satisfied with their treatment results.

How long is the hospital stay for the surgery?

A 1–2 day stay is usual; fast recoverers may leave the same or next day.

How long does the urinary catheter stay in?

The catheter usually stays 1–3 days after surgery and is removed once you can urinate on your own.

Does robotic waterjet surgery (Aquablation) have side effects or complications?

Temporary blood in the urine, painful urination, or incomplete emptying may occur but usually clear within days. Sexual function (erection, ejaculation, etc.) is preserved more often than with heat-based procedures.

Even with the same equipment, Aquablation therapy outcomes can vary depending on how the resection range is set and which function-preservation strategy is used, so surgical planning experience and the treatment system are important factors. In particular, a precise surgical plan is needed that considers not only urinary symptom improvement but also preservation of ejaculatory function. With this in mind, Goldman Urology Clinic performs Aquablation therapy centered on precise surgical design rather than on the equipment alone.

First, drawing on over 600 surgical cases accumulated since the procedure's early adoption in Korea, we plan the resection range to suit each patient's prostate size and shape, and we use real-time ultrasound imaging together with AI-based surgical planning to perform millimeter-precise resection.

To preserve the microstructures around the verumontanum involved in ejaculatory function, we apply the Hood Sparing technique, which has reduced the rate of retrograde ejaculation to ½ of the previous level. This approach, which addresses urinary improvement and functional preservation together, may help lower the likelihood of retrograde ejaculation.

After surgery, we continue to manage the recovery process reliably through a follow-up care program and an overnight on-call system in the inpatient ward, which check changes in urinary symptoms and the state of functional preservation step by step.

What defines Aquablation at Goldman is a systematic process, from precise preoperative planning and function-preserving strategies to postoperative recovery care.
When choosing a hospital for Aquablation, check not just whether it has the equipment but also its actual surgical experience, planning that accounts for functional preservation, and its postoperative care system.Because Aquablation sets the resection range precisely with a robot and real-time ultrasound, results depend on the medical team's experience and the hospital's treatment system.

Therefore, it helps to also review the following criteria.
- A board-certified urologist and a dedicated prostate clinic - Aquablation case volume and experience with very large prostates - Planning based on real-time ultrasound and a strategy that considers functional preservation - Follow-up care that checks both urinary improvement and sexual function after surgery (such as an overnight on-call system in the inpatient ward)

With Aquablation, outcomes vary with the resection range and function-preserving strategy even on the same equipment, so confirm the medical team has enough clinical experience and can plan the procedure precisely.

For example, Goldman Urology performs Aquablation drawing on over 600 surgical cases since the procedure's early adoption in Korea, tailoring the resection range to each patient's prostate structure.AI-based planning with real-time ultrasound enables millimeter-precise resection, and the Hood Sparing technique, which accounts for the microstructures around the verumontanum tied to ejaculatory function, is applied.

After surgery, a follow-up program (with an overnight on-call system in the inpatient ward) tracks urinary improvement and functional preservation, guiding recovery step by step toward more stable outcomes.
