1、 Revolutionary breakthrough in stone treatment

(1) Digital ureteroscope (fURS)

Tæknileg bylting:

4K digital imaging (such as Olympus URF-V3): resolution increased to 3840 × 2160, stone recognition rate increased by 30% compared to fiber optic microscopy.

271 ° active bending: The success rate of reaching the renal pelvis has increased from 65% in traditional endoscopy to 98%.

Clinical breakthrough:

Combined holmium laser (such as Lumenis Pulse 120H) lithotripsy can achieve a single stone clearance rate of over 90% for kidney stones below 2cm.

Tubeless surgery: No double J tube is left after surgery, and the patient is discharged on the same day.

(2) Ultra fine percutaneous nephroscopy (UMP)

Tæknilegir atriði:

13Fr channel (approximately 4.3mm): reduces trauma by 80% compared to standard PCNL (24-30Fr).

Negative pressure stone removal system (such as ClearPetra): real-time suction of gravel, renal pelvis pressure<20mmHg (to avoid infection spread).

Data comparison:

(3) Real time analysis of stone composition

Laser induced breakdown spectroscopy (LIBS):

Instantly determine the composition of stones (such as uric acid/cysteine) during surgery and guide postoperative dietary adjustments.

Data from the University of Munich in Germany shows that the recurrence rate of stones has decreased by 42%.

2、 Precision and minimally invasive treatment of tumors

(1) Blue laser complete resection of bladder tumor

Tæknilegir kostir:

The 450nm wavelength laser selectively vaporizes tumors, with a precise depth control of 0.5mm.

Compared to traditional electrocautery, the incidence of obturator reflex has decreased from 15% to 0%.

Klínísk gögn:

The one-year recurrence rate of nonmuscular invasive bladder cancer (NMIBC) was only 8% (24% in the resection group).

(2) 3D printed navigation for partial nephrectomy

Operation process:

step 1. Print a transparent kidney model based on CT data and mark the tumor boundary.

step 2. Combined with fluorescence laparoscopy (such as da Vinci SP) for precise resection while preserving normal renal units.

Meðferðaráhrif:

The negative rate of tumor margins is 100%, and the glomerular filtration rate (GFR) only decreases by 7%.

(3) Prostate steam ablation (Rez ū m)

Mechanism:

103 ℃ steam is injected through the urethra to precisely ablate hyperplastic glands (avoiding urethral mucosa).

Kostir:

Outpatient services can be completed within 15 minutes, with a sexual function preservation rate of over 95% (compared to 60% for TURP).

3、 Endoscopic innovation for obstructive diseases

(1) Intelligent bracket system

PH responsive ureteral stent:

When the pH of urine is above 7, it will automatically expand to relieve obstruction, and when the pH is normal, it will retract (to avoid long-term retention).

Biodegradable stent:

The polylactic acid material is fully absorbed within 6 months and does not require secondary removal.

(2) Endoscopic urethral suspension surgery

Treatment of female stress urinary incontinence:

Transvaginal Urethral Tensionless Suspension (TVT-O), surgery time<20 minutes.

The cure rate is 92%, which is a 90% reduction in trauma compared to open surgery.

4、 Andrology and Functional Urology

(1) Seminal vesicle endoscopy technique

Breakthrough applications:

A 0.8mm ultra-thin mirror was used to retrograde ejaculate through the ejaculatory duct for the treatment of hematospermia (success rate of 96%).

Discovery and electrocoagulation of seminal vesicle stones/tumors, preserving fertility function.

(2) Robot implantation of penile prosthesis

Da Vinci SP kerfið:

Single hole approach completes the dissection of the corpus cavernosum, reducing vascular and nerve damage.

The recovery time of postoperative erectile function has been shortened from 6 weeks to 2 weeks.

5. Tæknilegar framtíðarstefnur

(1) AI Stone Warning System:

Like Dario Health's urine analysis AI, predicting stone risk 3 months in advance.

(2) Nano robot endoscope:

The magnetic nanorobot developed in Switzerland can actively remove small renal pelvis stones.

(3) Organ chip simulation:

Simulate the endoscopic operation path on the chip before surgery to reduce the learning curve.

Tillögur að framkvæmdarstefnu

Primary hospitals: Prioritize the configuration of holmium laser and digital ureteroscope, covering 90% of stone cases.

Third class hospital: Establish a robotic endoscopy center to carry out complex surgeries such as prostate cancer cryoablation.

Research focus: Developing molecular imaging endoscopy (such as PSMA targeted fluorescence) for the localization of small tumors.

These technologies are reshaping the treatment paradigm of urology through three core advantages: sub millimeter precision, physiological function preservation, and rapid rehabilitation. It is expected that by 2026, 70% of urological surgeries will be completed through natural endoscopic procedures.
