How to Maximize the Benefits of Recent Advances in Urology and Urethral Stricture Surgery
There have been several recent advancements in urology, including new treatments and technologies.
Here are a few examples:
- Prostate cancer screening: prostate cancer screening has been a controversial topic, but recent advancements in imaging and biomarker testing are improving the accuracy of screening and reducing unnecessary biopsies. For example, the Prostate Health Index (PHI) and 4Kscore tests can help identify men at high risk for prostate cancer and may benefit from further testing. Focal therapy for prostate cancer
- Focal therapy is a minimally invasive treatment for prostate cancer that targets only the cancerous tissue while sparing the healthy tissue. Several new focal therapy techniques are being developed, including high-intensity focused ultrasound (HIFU) and cryotherapy.
- Robotic surgery: Robotic surgery has become increasingly common in urology, allowing for more precise and minimally invasive procedures. Urosurgeons use the da Vinci surgical system for prostatectomies, kidney surgeries, and other urological procedures.
- Extracorporeal shock wave lithotripsy (ESWL): ESWL is a non-invasive treatment for kidney stones that uses shock waves to break up the kidney stones to pass in easily. New advancements in ESWL technology, such as the Dornier Delta III lithotripter, are improving the effectiveness and safety of the procedure.
- UroLift system for enlarged prostate: The UroLift system is a minimally invasive treatment for benign prostatic hyperplasia (BPH) or enlarged prostate. The procedure involves placing small implants in the prostate to lift and hold the enlarged tissue out of the way, relieving pressure on the urethra and improving urine flow. The UroLift system is safe and effective in clinical trials.

Overcoming complications in urologic surgery requires a multifaceted approach, including appropriate preoperative evaluation, meticulous surgical technique, and vigilant postoperative care.
Here are some strategies for preventing and managing complications in urologic surgery:
- Preoperative evaluation: an appropriate preoperative evaluation is essential to identify patients at increased risk for complications. This process may include a thorough medical history and physical test, laboratory tests, and imaging studies. Patients with underlying medical conditions, such as diabetes or heart disease, may require additional evaluation and management.
- Meticulous surgical technique: Meticulous surgical procedure is critical to reducing the risk of complications. This procedure includes careful dissection, adequate hemostasis, and attention to detail when closing incisions. Surgeons should also be familiar with the latest surgical approaches and technologies, such as laparoscopy and robotic surgery, to minimize tissue trauma and improve patient outcomes.
- Intraoperative monitoring: Intraoperative monitoring, such as continuous electrocardiogram (ECG) and blood pressure monitoring, can help detect and manage complications during surgery. In addition, proper use of intraoperative imaging, such as fluoroscopy or ultrasound, can help guide surgical decision-making and reduce the risk of injury to surrounding structures.
- Postoperative care: Vigilant postoperative care is essential to managing complications and promoting patient recovery. This action may include close monitoring of vital signs, management of pain and nausea, early ambulation, and physical therapy. Patients should also be educated on potential signs and symptoms of complications, such as fever, bleeding, or infection, and instructed to seek medical attention promptly if they occur.
- Multidisciplinary approach: Urologic surgery often requires an associative approach involving collaboration between urologists, anesthesiologists, nurses, and other healthcare providers. This team-based approach can help optimize patient care and minimize the risk of complications.
In summary, preventing and managing complications in urologic surgery requires a comprehensive approach that includes appropriate preoperative evaluation, meticulous surgical technique, and vigilant postoperative care.

Urethral stricture is a narrowing of the urethra, the tube that carries urine from the bladder out of the body. This narrowing can cause difficulty urinating, frequent urination, urinary tract infections, and other complications.
There have been several recent advancements in the treatment of urethral stricture, including:
- Endoscopic treatments: Endoscopic treatments, such as urethrotomy and urethral dilatation, involve using a small camera and instruments inserted into the urethra to remove or stretch the narrowed area. Urosurgeons perform these procedures in minimally invasive and on an outpatient basis.
- Urethroplasty: Urethroplasty is a surgical procedure that involves removing the narrowed area of the urethra and reconstructing it using healthy tissue. This procedure has a high success rate and can provide long-term relief of symptoms.
- Tissue engineering: Tissue engineering is an emerging field that involves growing new tissue in the lab and implanting it into the body to replace damaged tissue. Researchers are exploring the appropriate use of tissue engineering to create new urethral tissue for urethroplasty.
- Stents and grafts: Surgeons use Stents and grafts to treat urethral strictures by holding the urethra open or providing additional support to the reconstructed area. Manufacturers can use several materials to create medical devices, such as metal, silicone, and biological tissue.
- Laser therapy: Laser therapy is a minimally invasive treatment option that uses a high-energy laser to vaporize the narrowed area of the urethra. This procedure can be done on an outpatient basis and has a lower risk of complications than traditional surgery.
Broadly, the treatment of urethral stricture depends on the severity of the narrowing and the individual patient's circumstances. A urologist can help determine the best course of treatment for each patient.
There are several surgical procedures for urethral strictures, and the complexity of the surgery will depend on the location, length, and severity of the urethral stricture. Some of the most complicated urethral stricture surgeries include:
- Buccal mucosa urethroplasty: This surgical procedure involves using tissue from the inside lining of the cheek (buccal mucosa) to reconstruct the urethra. It is for sizeable and more severe restrictions.
- Johanson's urethroplasty: This is a complex surgical procedure that involves removing the strictured segment of the urethra and then rejoining the two ends with a graft. Surgeons take the graft from the patient's tissues or a donor.
- Perineal urethrostomy: This involves creating a new opening in the urethra through the perineum (the area between the anus and the scrotum in men). Surgeons use the procedure as a reserve for patients who have failed other treatments or have extensive scarring.
- Penile skin flap urethroplasty: This complex surgical procedure involves using skin from the penis to reconstruct the urethra. Doctors use it for strictures located in the penile urethra.
- Dorsal onlay graft urethroplasty: This obscure surgical procedure involves placing a graft on the top of the urethra to reconstruct it. Doctors use this procedure for urethral strictures in the bulbar urethra.
It is important to note that all surgical procedures carry risks, and the choice of surgery will depend on the individual patient's condition and the surgeon's expertise. Patients should discuss the risks and benefits of each procedure with their surgeon.
