The Pitt is not complete until they have a difficult foley and the urologist they call grills them on which catheters they tried, who tried and say they’re not coming in until the doctor themselves try. And then they come in and place it in 3 seconds.

📌Pure Antegrade Approach for Optimal Nerve-Sparing
📝Nerve-sparing in radical prostatectomy is difficult, with outcomes varying by technique. Management of the Sch?ller pedicle affects nerve preservation. I advocate the pure antegrade method, leaving the bundle circumferentially as one fascial layer.

ERRÓNEAMENTE se cree que el CALCIO AUMENTA riesgo de formar CÁLCULOS RENALES.

Sin embargo consumirlo en la dieta (aprox 1-1.2 grs/día) es fundamental para prevenirla, no para causarla, desmintiendo el mito.

Esto porque el calcio dietético atrapa el oxalato en el intestino, reduciendo absorción y excreción en la orina.

Así que si tu médico te prohíbe la leche, cambia de médico. 👍🏻

As a Urologist, I believe this post from @EricTopicus is seriously misleading.
Readers and our patients need to recognize that.

This RCT in @Lancet was not designed to test whether increasing fluid intake prevents stone recurrence. Rather, it evaluated the effectiveness of a personalized “fluid prescription” program vs usual care.

When you understand what they want to test, you will become clear why no difference was observed between the two groups between the intervention group (the fluid prescription” vs control group (usual care)

Moderate consumption of caffeinated coffee or tea was linked to reduced #dementia risk and modest improvements in #cognitive outcomes; no benefit was seen for decaffeinated coffee in an observational study of US adults.

Management of testicular torsion:
- US with high false negative rate
- if high TWIST score, do surgery
- detorse and warm testicle while you do contralateral orchiopexy

Here we go! Another excellent review from @RadioGraphics: “Retroperitoneum and Pelvic Extraperitoneum: Anatomic Landmarks, Imaging Features, and Patterns of Disease Spread” 🩻📊

A must-read deep dive—not just for radiologists, but for general surgeons, oncologists, ER docs & more!

✅ Complex fascial planes
✅ Key anatomy (vessels, lymphatics, nerves) on CT and MRI
✅ Disease spread patterns: fluid collections, hematomas, urinomas, abscesses, tumors (RCC, lymphoma, sarcomas), inflammation (pancreatitis, IgG4), trauma & beyond
✅ Flowcharts for diagnosis, mass classification & spread

🥇 Huge congrats to the Authors on this outstanding work!

RadioGraphics keeps delivering amazing content that helps doctors, trainees & patients—thank you 🙏

CURIOSIDAD🎄🎅 : Durante la navidad se MULTIPLICAN los casos de fracturas de pene.

🚩La Navidad se asocia con un 43% mayor prevalencia de fracturas de pene.

⏱️ Navidad, fines de semana y verano es cuando más fracturas de pene suceden.

😱 Las posturas que implican una flexión forzada del pene erecto son las de mayor riesgo: ejemplo El “Reverse cowgirl”.

Doctors for generations accepted being at the mercy of their pagers. Now, younger physicians are questioning medicine’s workaholic culture.

Prostate cancer Out on The Lancet

https://t.co/GvcI3AIr86

#ProstateCancer is a leading cause of cancer-related death worldwide, though recent advances have substantially improved its management and outcomes. Current approaches favor active surveillance for indolent disease, local therapies for curative treatment, and systemic options—including androgen deprivation therapy, chemotherapy, and emerging targeted agents such as PSMA radioligand therapy and PARP inhibitors—for advanced or metastatic disease, with treatment decisions guided by toxicity, patient preferences, and the need for further research on optimal therapy sequencing.

ctDNA-guided adjuvant atezolizumab in muscle-invasive bladder cancer
@tompowles1 @cdanicas @AndreaNecchi @DrYukselUrun @dralvaropinto @OncoBellmunt
🔍 Phase III evaluating ctDNA-guided adjuvant immunotherapy after cystectomy.
🧪 Only ctDNA-positive patients randomized (n=250).
💊 Atezolizumab doubled DFS → 9.9 vs 4.8 mo (HR 0.64).
🕯️ OS benefit confirmed → 32.8 vs 21.1 mo (HR 0.59).
🧼 Persistent ctDNA-negative patients: 95% DFS at 1 yr, avoiding unnecessary treatment.
🔁 Higher ctDNA clearance with atezolizumab.
📌 Supports MRD-guided adjuvant therapy as a new standard in MIBC.
