Advancements in Reconstructive Urologic Surgery

Introduction:

A wide range of disorders affecting the upper and lower urinary tracts are included in reconstructive urology. The specialism has grown over the previous few decades into a broad field that now includes plastic surgery, incontinence, prosthetics, cancer survivorship, and robots. A recent mission statement released by the Society of Genitourinary Reconstructive Urologic Surgery highlighted the goal to encourage and support research in the expanding domains of tissue engineering, device design, patient-reported outcomes, and validated assessment tools for urethral stricture illness.

What Are the Types of Reconstructive Urology Procedures?

For both men and women, healthcare provides a comprehensive spectrum of reconstructive procedures:

• Bladder Reconstruction: Bladder reconstruction is frequently paired with large pelvic cancer surgeries and is necessary for the treatment of injuries or tumors in the pelvic region.

• Genital Reconstruction: To treat genital damage, genital malignancies, congenital malformations, and Peyronie's disease, surgery to repair the penis and scrotum is frequently required.

• Treatment for Neurogenic Bladder: For certain people, robotically assisted bladder augmentation may be a viable alternative if nerve injury is the source of their bladder problem.

• Penile Prosthetics: Procedures such as implants help men who have erectile dysfunction or urine incontinence regain their appearance and functionality.

• Ureter Reconstruction: To treat urethral blockages, such as those brought on by trauma or ureteral stricture, treatments such as minimally invasive techniques and sophisticated bladder reconfiguration are available.

• Repair of Obstructions at the Ureteropelvic Junction (UPJ): Robotic pyeloplasty, a minimally invasive procedure, is the first choice when treating obstructions at the ureter-kidney junction.

What Are the Techniques of Advancements in Reconstructive Urologic Surgery?

• Pyeloplasty: Urine flow obstruction from the renal pelvis to the proximal ureter is known as ureteropelvic junction obstruction. Dismembered pyeloplasty is commonly used to treat this, frequently owing to internal ureteral stenosis or external pressures from crossing arteries.

• The Reimplantation of Ureter: Patients with traumatic distal ureteral injury, distal ureteral strictures, or vesicoureteral reflux are treated by ureteral reimplantation. Historically, open surgery has been the gold standard, with success rates ranging from 95 to 99 percent. The increased desirability of robotic ureteral reimplantation can be attributed to similar results with lower morbidity.

• Boari Flap: The Boari flap is a bladder flap repair procedure used to treat longer segment distal ureteral strictures. The Boari flap can be used to rebuild ureteral defects up to 15 inches in length, but standard ureteral reimplantation is limited to short deficits of four to five cm.

• The Ureterocalicostomy: An anastomosis between a section of the ureter and the calyceal system is created during the surgery. Ureterocalicostomy patients who cannot mobilize their ureter for a pyeloplasty and have proximal ureteral strictures with a dilated lower pole collecting system might consider this treatment.

• Onlay Appendix: The bladder might not be able to reach mid- or proximal-ureteral strictures, in which case different reconstruction techniques are required. Distal ureteric strictures can be treated using reimplantation techniques. An example of this method is appendiceal interposition. Reggio initially reported the laparoscopic appendiceal onlay procedure, which covers the longitudinally opened ureter with a tabularized appendix section.

• Ureteroplasty of the Buccal Cavity: For patients with lengthier or multifocal proximal ureteral strictures without ureteroureterostomy, buccal urethroplasty reconstructs the ureter. The buccal mucosa is a great method when inadequate blood supply to the reconstruction could be a concern because it can be perfused through various surfaces.

• The Ileal Ureter: Due to its robust blood supply and excellent mobility, the ileum has historically been used to repair the ureter.

• The Internal Ileal Duct: Robotic intracorporeal laparoscopic ileal conduit after cystectomy. Five 12 mm (millimeter) trocars are positioned in a diamond pattern with the patient supine. Proximally up to the kidney's lower pole and distally to the left vesicoureteral junction, the ureters were located and mobilized.

• The Neobladder: The neobladder is a reconstructive operation that gives patients a reservoir that mimics the storing and voiding of a normal urinary tract using various tiny or big bowel segments. This procedure may have some psychological benefits.

• Repair of Ureteroenteric Anastomotic Strictures: Urinary diversion may result in ureteroenteric anastomotic strictures, which have been reported to occur three to ten percent of the time in the literature. It is thought that ureteral ischemia is the cause of strangulations. Urinary blockage, infection, stones, and loss of renal function are some of the symptoms associated with stricture, while some patients may not experience any symptoms. Most strictures have been observed to appear seven to 18 months after surgery.

• Bladder Excision Surgery: Congenital weakening of the bladder wall or disorders like benign prostatic hypertrophy or urethral strictures that raise intraluminal bladder pressure can cause bladder diverticula. Diverticula have been linked to a higher incidence of cancer, stones, and UTIs.

• Cystoplasty Augmentation: A technique called augmentation cystoplasty is used to decrease intravesical pressure and expand the bladder's capacity. There is no clear benefit to using one of the several other procedures of cystoplasty that have been documented, such as gastrocystoplasty, ureterocystoplasty, autoaugmentation, seromuscular augmentation, alloplastic replacement, or the use of bioprosthetic materials.

• Reconstruction of the Bladder Neck: Bladder neck reconstruction aims to address bladder neck contracture (BNC)-related incontinence. Although uncommon, bladder neck pathology frequently arises as a result of pelvic trauma, radical or simple prostatectomy problems, or it may be absent or compromised from birth in cases of epispadias.

• Retrograde Urethroplasty: As it is located behind the pubic bone and there is a chance of urine incontinence, posterior urethral reconstruction presents a special surgical challenge. The majority of the restrictions in this area are post-traumatic. However, they can also result from radiation or earlier instrumentation.

• Vaginal Transgender Surgery: The best course of action for patients who have a strong and ongoing cross-gender identity is gender-affirming surgery. Clinical guidelines follow a step-by-step protocol that includes hormone therapy, real-world experience and psychotherapy, surgical therapy, and diagnostic assessment.

Conclusion:

Due to its accuracy, convenience of use, and promising results, surgery has had enormous growth and acceptance. It has quickly become a vital instrument in the reconstructive urologist's toolbox. With ongoing uptake and improvement, robotic reconstructive urology has a bright future.
