🔰Bladder Injury

🔷Mechanisms Of Bladder Injury
📍1. Iatrogenic Injury During :
▪︎TURBT (TransUrethral Resection Of Bladder Tumours Most Common Iatrogenic Cause)

▪︎Anti-Incontinence Surgery

▪︎Pelvic Surgery (Hysterectomy/CS/ColoRectal Surgery)

📍2. After Abdominal Trauma Or Pelvic Fractures (Most Common Non-Iatrogenic Causes)

📍3. Spontaneous Rupture After Bladder Augmentation Due To OverDistention (in Patients With Limited Bladder Sensation)


🔷Types Of Bladder Injury
📍1. ExtraPeriToneal (Most Common 65%) :
▪︎Urine Leakage into RetroPubic Space With Intact Peritoneal Membrane

📍2. IntraPeriToneal (25%) :
▪︎Urine Leakage into The Peritoneal Cavity Due To Injury To The Peritoneal Membrane Over The Bladder

▪︎High Risk Of Urine Peritonitis & Ileus & More Complications

📍3. Mixed (Extra & Intra Peritoneal)

📍4. Only Bladder Contusions (No Urine Leakage)


🔷Grades Of Bladder Injury
📍1. Only Contusions & IntraMural Hematoma Or Partial Thickness Lacerations

📍2. ExtraPeriToneal Bladder Wall Lacerations <2cm

📍3. ExtraPeriToneal ≥2cm Or IntraPeriToneal <2cm

📍4. IntraPeriToneal ≥2cm

📍5. Lacerations Extending into Bladder Neck Or Trigone (Urethral Orifice)


🔷Clinical Features & Dx Of Bladder Injury
📍1. SupraPubic Pain

📍2. Not Able To Pass Urine

📍3. Hematruia

📍4. Abdominal Distention

📍5. Urine Peritonitis

📍6. Confirm Dx (Retrograde CytoGram Or CT CystoGram) :
▪︎Leakage Of Contrast Limited To The Area Surrounding The Bladder (Flame Shape) ➡ ExtraPeriToneal Leakage

▪︎Contrast Surrounding The Bowel ➡ IntraPeriToneal Leakage


🔷Mx Of Bladder Injury
📍1. ExtraPeriToneal Injury :
🔻I. Urethral Catheterization For 10-14 Days (Allows Spontaneous Healing)

🔻II. Immediate Repair For :
▪︎Iatrogenic Bladder Injury If Identified During Operation

▪︎Bladder Repair During Operations For Pelvic Fracture Or Rectal Or Vaginal Perforation Repair


📍2. IntraPeriToneal Injury :
🔺I. Open Surgical Repair

🔺II. Bladder Catheterization With Close Monitoring ➡ For Small IntraPeriToneal Leakage & Stable Patient

🔰 Bladder Anomalies
📍1. Bladder Exstrophy :
▪︎Failure Development Of The Lower Part Of The Anterior Abdominal Wall Results in Exposure Of The Bladder To The Outside

▪︎More in Males

▪︎Associated With :
🔺I. EpiSpadias (Anterior Opening Of The Urethra)

🔺II. Diastasis Of The Symphysis Pubis/Waddling Gate

🔺III. Wide Pubic Bones/External Rotation Of Anterior & Posterior Bony Pelvis (Results in Outward Rotation Of Lower Limbs)

🔺IV. Short Penis & Vagina & Bifid Clitoris

🔺V. Incontinence & VUR

🔺VI. Low Set Umbilicus With Triangular Shape Fascial Defect in The Lower Abdomen & High Risk Of indirect Inguinal Hernia

🔺VII. Rectal Prolapse/Imperforated Anus/Short Perineum/Anteriorly Displaced Anus

▪︎Need Surgical Correction Of The Anomalies



📍2. Bladder Diverticulae :
▪︎It's Protrusion (Out-Pouching) Of Some Bladder Wall Layers (Mucosa) Through Wall Weakness To The Outside

🔻I. Acquired Diverticulae (Secondary) Occurs in :
▪︎Adult Men With BPH (Most Common)

▪︎Children With Posterior Urethral Valve (Infra-Vesical Obstruction) Or NeuroGenic Bladder (Detrusor Sphincter Dyssynergia DSD)

▪︎Characterized By Elevated Bladder Pressure & Thick Bladder Walls (Trabeculations) & Multiple Diverticulae


🔻II. Congenital Diverticulae (Primary) :
▪︎It's Bladder Wall Mucosal Herniation Through Congenital Muscular Weakness (Defect) Between Intra-Vesical Ureter & Roof Of Ureteral Hiatus (Hutch Diverticulum)

▪︎Associated With VUR

▪︎Characterized By Normal Bladder Pressure & Thin Walls & Usually Single Diverticulum


🔻III. Clinical Features & Dx & Mx Of Bladder Diverticulae :
▪︎Asymptomatic (Usually in Small Congenital Diverticulae)

▪︎Hematruia (30%)

▪︎Recurrent UTI & Bladder Stones

▪︎Urine Retention & Hydronephrosis

▪︎Risk Of Malignancy (1%)

▪︎Dx ➡️ US/CT/MRI/CystoGram/Cystoscope

▪︎Mx ➡️ Surgical Correction Only If Symptomatic (Bladder Outlet Obstruction) Or Malignancy Developed

🔴Bladder Cancer

▪︎Usually Transitional Type Arise From The UroThellium Of The Bladder

▪︎More in Men

▪︎Usually Superficial Low Grade Tumour With Good Prognosis (70-90% 5-Year Survival Rate)

▪︎High Grade Tumours (Muscle Invasion) Has 10-60% 5-Year Survival Rate

▪︎UroThelial Tumours Can Affect Other Parts Of Urinary Tract (Renal Pelvis/Ureter/Urethra)


🔷Risk Factors For Bladder Cancer
📍1. Smoking (Most Common)

📍2. Occupational & Environmental Exposure To Tanner/Rubber/Paints & Dyes/Gas & Tar/Arsenic in Water/HairDressers/Plumbers/Painters

📍3. Chronic Bladder Inflammation Results in Squamous Metaplasia Then Squamous Carcinoma (Catheter/Stones/Recurrent UTI/Schistosomiasis)

📍4. Drugs (Phenacetin/Cyclophosphamide)

📍5. Pelvic Radiation


🔷Types Of Bladder Cancer
📍1. Transitional Cell Carcinoma (Most Common >90%)

📍2. Squamous Cell Carcinoma (1-7%) ➡️ Usually Occurs Due To Chronic Inflammation in The Bladder (Stones/Prolonged Catheterization/Schistosomiasis)

📍3. Adenocarcinoma (2%) ➡️ Arise in The Dome Of The Bladder (Urachus) Or From Bowel Tissue Present in The Bladder (During Augmentation Entero-CystoPlasty Or Bladder Extrophy Repair)


🔷Clinical Features & Dx Of Bladder Cancer
📍1. Painless Visible Hematruia (Most Common Presentation 85%)

📍2. Lower Urinary Tract Symptoms (Frequency/Urgency/DysUria)

📍3. Recurrent UTI

📍4. Features Of Advanced Malignancy :
▪︎Flank/Pelvic/Bone Pain
▪︎Weight Loss
▪︎Lower Limb Edema

📍5. Confirm Dx :
▪︎Urine Exam & Culture & Cytology (Looking For Malignant Cells)

▪︎CT UroGram (Gold Standard)

▪︎CystoUrethroScopy & Biopsy (Direct Visualization Of The Bladder For Patients With Suspicious Of Cancer)


🔷Mx Of Bladder Cancer
📍1. No Bladder Muscle Invasion (NMIBC) :
▪︎TransUrethral Resection Of The Bladder Tumours (TURBT)

▪︎Then IntraVesical Chemotherapy To Reduce Risk Of Recurrence (MitoMycin C Course For 6w)

▪︎Then Regular Follow Up Using Cystoscope

▪︎IntraVesical BCG For Patients With Bladder Carcinoma in Situ (CIS Have Risk Of Progression into Bladder Cancer But Response To BCG)


📍2. Bladder Muscle Invasion (MIBC) :
▪︎Chemotherapy (Neoadjuvant) Then Radical CysteCtomy With Urinary Diversion (Preferred For Patients <70 Years Of Age)

▪︎Chemo-RadioTherapy Only (For Older Patients)


🪀Methods Of Urinary Diversion :
🔺I. OrthoTopic Bladder :
▪︎Creates New Bladder Pouch From Colon Or Small Bowel Tissue Then Connect it To The Urethra

▪︎Used When The Urethra Intact (in Good Condition)

▪︎Studer Pouch Most Commonly Performed

▪︎Not Used If There's Widespread Bladder Carcinoma in Situ (CIS) Or Tumours in The Prostatic Urethra


🔺II. Cutaneous Diversion (HeteroTopic Bladder) :
▪︎Connecting The Ureters To The Appendix Or Ileum

▪︎Then Creates Opening in The Skin (Stoma Near Umbilicus Or RIF) For Self Catheterization

▪︎Used When Urethra Removed Or Not-Functioning

▪︎Ileal Conduit is The Best Method Due To Low Risk Of Complications


🔺III. UretroSigmoidoStomy :
▪︎Attach Ureters To Sigmoid Colon So Urine Pass With Faeces

▪︎Need Good Anal Sphincter Function (To Prevent Incontinence Of Urine)

▪︎High Risk Of Complications (Ascending UTI/Malignancy/Bowel Frequency/Urge Incontinence/Metabolic Disturbances)

اقرأوا هذه المعلومة الحلوة كتبتها لكم وخلوها في بالكم … وبعدها ارقدوا 😁

- تخيل أن مريض قد أجرى عملية استئصال الزائدة الدودية سابقا… ومع ذلك يعود بنفس ألم الزائدة الكلاسيكي (ألم يبدأ حول السرة ثم ينتقل للربع السفلي الأيمن، غثيان، قيء، وارتفاع كريات الدم البيضاء)!

🗣️ أثناء أخذ القصة المرضية يقول لك المريض:
"قد استأصلت الزائدة من قبل!"

والفحص السريري يبيّن وجود Scar في مكان العملية ⬅️ هنا مباشرةً تفكيرك بيروح لتشخيصات أخرى مثل النزلة المعوية وغيرها

❗️لكن المفاجأة: ما زالت ممكن تكون التهاب في الزائدة الدودية!

📌 في حالة نادرة قد تحدث مرة من بين كل 500 الف عملية تُسمى Stump Appendicitis وهي التهاب يحدث في الجزء المتبقي من الزائدة بعد استئصالها (appendiceal stump)، وتحدث بنسبة اكبر عند ترك جزء طويل أثناء العملية.

❇️ المعلومة المهمة:
قد يحدث التهاب الزائدة الدودية بعد أيام أو حتى سنوات من الاستئصال

العلاج: استئصال الجزء المتبقي جراحيًا (completion appendectomy)
