Kidney Transplant II: Surgical Procedure

220
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Ureters01:22

Ureters

1.2K
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

Anatomy of the Genitourinary System I: Kidneys and Ureters

374
The upper urinary system comprises two kidneys and two ureters, which are crucial in filtering blood and forming urine.KidneysLocation and Structure:The kidneys are two bean-shaped organs positioned behind the peritoneum on either side of the spine.Kidneys are between the 12th thoracic (T12) and the 3rd lumbar (L3) vertebrae.The position of the liver causes the right kidney to sit slightly lower than the left.Protective Layers:Each kidney is enveloped in a tough, fibrous membrane called the...

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

1.8K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Urologic Endoscopic Procedure: Cystoscopic Examination

1.5K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

764
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Area of Science:

  • Urology
  • Surgical Innovation
  • Reconstructive Surgery

Background:

  • Long ureteral strictures pose significant challenges in reconstructive urology.
  • Traditional treatments may have limitations for extensive ureteral defects.

Purpose of the Study:

  • To evaluate the long-term efficacy of ureteral reconstruction using the appendix for extensive ureteral strictures.
  • To assess the functional outcomes and complication rates associated with this reconstructive technique.

Main Methods:

  • A cohort of 26 patients with long ureteral strictures underwent ureteral substitution with the appendix between 1998 and 2019.
  • A novel surgical technique involving a cecal flap for improved appendicovesical anastomosis was employed in 22 cases.
  • Follow-up ranged from 1 to 21 years, monitoring for strictures, kidney function, and overall outcomes.

Main Results:

  • Overall success rate was high, with 96.2% of patients achieving good long-term results.
  • Kidney function was restored in all patients.
  • Complications included stricture of the uretero-appendical anastomosis in 15.4% of cases, managed with various interventions.

Conclusions:

  • Appendix reconstruction is a successful method for restoring upper urinary tract function in patients with long ureteral strictures.
  • The technique, particularly with modifications for anastomosis, offers durable and effective solutions for complex ureteral defects.
