Summary
Pregnancy commonly causes kidney dilation, which can lead to infections. Endoureteral prosthesis can be a treatment option for selected cases requiring renal drainage during pregnancy.
Area of Science:
- Obstetrics and Gynecology
- Urology
Context:
- Physiological hydronephrosis of pregnancy is common, particularly on the right side.
- While often asymptomatic, it can rarely lead to complications like pain and urinary tract infections.
- These complications can pose risks to both the mother and fetus.
Purpose:
- To review the authors' experience with endoureteral prostheses for renal bypass during pregnancy.
- To detail the technical aspects and indications for this specific drainage procedure.
Summary:
- Dilatation of the renoureteral cavities (kidney dilation) during pregnancy is a frequent condition.
- Although usually asymptomatic, it can occasionally cause pain or urinary infections, potentially leading to severe infectious and obstetrical issues.
- Renal cavity drainage via an endoureteral prosthesis is considered for very select cases.
Impact:
- Provides insights into managing a common pregnancy-related condition.
- Highlights a potential treatment option for complicated cases of pregnancy-related hydronephrosis.
- Informs clinical decision-making regarding renal drainage in pregnant patients.

01:21Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...
01:25Urinary Tract Calculi VI: Surgical Management
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

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 donor...
01:22Imaging Studies V: Intravenous Urography and Retrograde Pyelography
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.

01:28Urologic Endoscopic Procedure: Cystoscopic Examination
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...
