Bladder leaks in men are common — but they are NOT something you should ignore.

Many men assume urinary leakage is just part of ageing, something to “live with”. That’s simply not true.

Bladder leaks can be a sign of:
• Prostate enlargement
• Overactive bladder
• Nerve-related conditions (e.g. diabetes, stroke)
• Or side effects after prostate surgery

The good news? Most cases are treatable — often with simple, minimally invasive solutions when addressed early.

I’ve put together a short, easy-to-read guide on when bladder leaks should prompt you to seek medical advice, and what can be done about it.

👉 Read the full article here:

https://mtalvernia.sg/news/ask-the-experts-bladder-leaks-when-you-need-to-seek-help/

If you or someone close to you is experiencing bladder leakage, don’t suffer in silence.
Help is available — and quality of life can be restored.

男性尿失禁很常见，但绝不是“正常老化”的一部分。

很多男性认为漏尿是年纪大了没办法避免的事，只能默默忍受。
这是一个常见的误解。

男性出现尿液渗漏，可能与以下因素有关：
• 前列腺肥大
• 膀胱过度活跃
• 神经相关疾病（如糖尿病、中风）
• 前列腺手术后的影响

好消息是：大多数尿失禁是可以治疗的。
越早评估，治疗方式越简单，效果也越好。

我特别整理了一份简明指南，帮助大家了解：
什么时候尿失禁需要尽快就医，以及有哪些治疗选择。

如果您或家人正被尿失禁问题困扰，
请不要再默默承受 — 这是可以改善的

A FIRST FOR HINOTORI OUTSIDE JAPAN — ROBOTIC RIGHT RADICAL NEPHRECTOMY WITH IVC THROMBECTOMY

Today marks a significant milestone in our robotic oncology journey.

We completed the first Hinotori robotic IVC thrombectomy performed outside Japan, together with a right radical nephrectomy for a renal tumour extending into the vena cava.

This is a complex operation traditionally managed with large open incisions and significant physiological burden. Delivering it robotically — and safely — reflects how far the technology and our surgical ecosystem have evolved.

For our team, this wasn’t just about completing a difficult case.
It was about proving that advanced robotic oncology can be delivered right here, at a level that matches global centres of excellence.

Malaysia isn’t just adopting robotics.
We are accelerating it.
We are shaping the next chapter of minimally invasive cancer care in the region.

More innovation ahead — and this case sets a powerful benchmark.

日本以外首例 Hinotori 机器人下的下腔静脉血栓取出术（IVC Thrombectomy）
联合右侧肾切除手术圆满完成

今天，对我们的机器人泌尿肿瘤团队来说，是一个具有标志性的里程碑。

我们顺利完成了 日本以外首例使用 Hinotori 机器人进行的下腔静脉血栓取出术，并同时为患者实施右侧肾脏根治性切除。
这类肿瘤累及下腔静脉的手术，以往多需大型开放式切口，手术创伤大、风险高、恢复慢。

如今，我们以高精准度的机器人系统完成此高难度手术，体现了本地手术团队的成熟度、技术实力，以及对患者带来更安全、更微创、更快速康复的承诺。

这不仅是一台成功的手术，
更是区域医疗水平向前迈进的一大步。

马来西亚不再只是“追上”先进技术，
我们正在加速、突破、并为区域的 #@微创癌症治疗设立新标准。

未来还有更多创新，
而今天，是一个强有力的开始。

For over two years, this gentleman lived with a catheter — unable to pass urine, told by many that surgery was too risky and his condition beyond repair.

But today, through robotic simple prostatectomy, we safely removed this 200-gram giant prostate and gave him back what he thought he had lost forever — the simple, human joy of normal life.

Medicine isn’t just about removing disease — it’s about restoring hope, dignity, and possibility.

At Allen Sim Urology, every patient’s story reminds us that no case is ever truly “inoperable” when innovation and compassion come together.



這位病人因攝護腺嚴重腫大，兩年來只能依靠導尿管生活。
他曾被告知「無法手術」，只能接受現實。

直到今天，透過機器人輔助的攝護腺剜除手術，
我們成功地完整移除這顆重達 200 公克的巨大攝護腺，
讓他終於能再次自然排尿，重拾生活的尊嚴與自在.

醫療的價值，不僅在於治癒疾病，
更在於重燃希望、恢復信心，讓病人重新擁抱人生.

在 Allen Sim Urology，我們始終相信——
只要結合科技與關懷，就沒有真正「無法手術」的病人。

A rewarding day at Johor Specialist Hospital, where I had the privilege of proctoring Dr. Lim Teck Chin on a robotic surgery case using the da Vinci system.
Robotic surgery allows us to perform complex operations through small incisions with greater precision, less pain, and faster recovery for patients.
What makes these sessions meaningful is not just the technology — it’s the collaboration, mentorship, and shared commitment to bringing world-class care closer to home.
Grateful to the surgical and nursing teams at Johor Specialist Hospital for their dedication and teamwork in making this possible.

🎯 5 Robotic Cases. 2 Platforms. 1 Goal: Precision Surgery.

This week at Allen Sim Urology, we completed five complex robotic procedures across two advanced platforms — da Vinci Xi and Hinotori.

✅ Inguinal hernia repair
✅ Simple prostatectomy
✅ Radical prostatectomy
✅ Partial nephrectomy
✅ Excision of recurrent kidney cancer

Each case brought unique challenges — from functional restoration to oncologic control — all executed with robotic finesse for faster recovery and superior outcomes.

🔧 Innovation meets versatility.
🤖 Powered by dual platforms.
💪 Driven by precision.

🧠 When Advanced Technology Meets Expert Care

A patient came to us recently with vague abdominal symptoms—only to discover a 13cm tumour deep in the retroperitoneum, pressing dangerously on the left kidney and colon.

In a single, carefully planned robotic surgery, we were able to:
🔹 Remove the entire tumour
🔹 Perform a left nephrectomy
🔹 Resect part of the colon

Thanks to the minimally invasive robotic approach, there was no need for a large incision, and most importantly—
💯 The patient recovered fully, with zero complications.

This is exactly why we do what we do—to offer patients not just treatment, but the safest, most effective path back to health.

If you or someone you love is facing a complex surgical diagnosis, know that there are options—and you don’t have to walk that path alone.

📩 Feel free to reach out for a consultation.



🧬 科技与专业的结合，带来康复的奇迹

**BPH & Prostate Cancer Awareness Forum – Jakarta**

Recently in Jakarta, I had the privilege of leading an in-depth discussion on BPH & prostate cancer awareness—an issue close to my heart and vital to the mission at Allen Sim Urology. Alongside esteemed colleagues from Hospital Makhota Melaka, Regency Specialist Hospital and HMI Medical Centre and a special thanks to Wijaya for her invaluable role as moderator - we explored the latest advancements in early detection and minimally invasive treatments.

At Allen Sim Urology, I believe in empowering every individual with knowledge. Whether you're a patient, a family member, or someone passionate about health, I encourage you to take proactive steps for your well-being. If you have any concerns or questions about your prostate health—even a small worry—I strongly advise scheduling a consultation or screening. Early action truly makes all the difference, and your decision to act could be life-saving.

Let's continue this conversation together. Share your thoughts, ask questions, and help spread awareness about the importance of early detection in the fight against prostate cancer.



**雅加达前列腺癌认知论坛**

最近在雅加达，我有幸主持了一场关于前列腺癌认知的深入讨论——这一议题不仅与我息息相关，也是 Allen Sim Urology 使命的重要组成部分。与来自 Mahkota Medical Centre、Regency Specialist Hospital 以及 Malaysia Healthcare 的尊敬同事们一道，再特别感谢 Wijaya为此次论坛贡献的宝贵见解，我们共同探讨了早期检测与微创治疗的最新进展。

在 Allen Sim Urology，我坚信知识赋能是健康管理的基石。无论您是患者、家属，或是关注健康的朋友，我都鼓励您积极采取措施关爱自己的健康。若您对前列腺健康有任何疑虑或问题——哪怕只是些许担忧——我都强烈建议您安排咨询或筛查。早期行动确实能改变一切，您的决定可能带来生命的转机。

让我们一同延续这场重要对话。请在评论中分享您的看法、提问，并帮助传播早期检测在抗击前列腺癌中的关键作用。
