Benign Prostatic Hyperplasia (BPH) has become the most
common disease that endangers the health of the elderly men.
With many possible preexisted conditions such as cardiovascular
disease etc., the sugical risk of the aged would be much higher.
Thus we established effective and safe laser technology in
minimally invasive surgery. Despite of the benefit patients may
gain from minimally invasive surgery when it comes to treating
urolithiasis and urological tumours, severe complications which
may result in nephrectomy or death have also raised awareness
both at home and abroad. Through this study, we have solved
these problems and get 11 patents. In this clinical reseach, we
have not only established new non-invasive surgical techniques,
but also creatively proposed several complication solutions and
We first introduce 2 μm thulium laser resection of prostatetangerine
technique (TmLRP-TT) to treat BPH, which is a
transurethral procedure that uses thulium laser fiber as the
surgeon's fingers to resect whole prostatic lobes off the surgical
capsule, similar to peeling a tangerine. With very little bleeding
during surgery, the effectiveness and safety of the surgery
has been remarkably increased. International academic circle
gives high praise for this achievement. So far, we have already
successfully performed in more than 1000 cases.
We first introduce thulium laser and holmium laser to
radically excise bladder neoplasm at home and abroad. Followup
visit indicated that compared with radical cystectomy, the
short-term survival rate of this procedure is almost the same.
With the bladder function preserved, the patients' postoperative
quality of life is much more improved.
Percutaneous nephrolithotomy (PCNL) is usually performed
with inflexible ureteroscope, which makes it difficult to capture
the stones hidden in calyces. By applying flexible ureteroscope
and flexible holmium laser fiber in treating complicated upper
urinary tract calculi, we successfully solve this problem and get
patent on flexible ureteroscope.
We are the first to perform nephron sparing surgery with
2um thulium laser. With few intraoperative blood loss, accurate
incision and rarely reported complications, we believe it's a new
approach to perform nephron sparing surgery.
Avulsion of ureteral mucosa is one of the severe complications
of ureteroscopic laser lithotripsy and may result in nephrectomy
or even death. Through this project, we discovered new method
to reconstruct ureteral mucosa using free grafts obtained from
peritoneum, impaired ureteral mucosa and bladder mucosa in
order to avoid nephrectomy.
Septic shock and lethal massive haemorrhage are two severe
complications that may result from PCNL. We proposed several
complication solutions and preventive measures for PCNL.
Project members have published 112 articles, 37 of them are
accepted by SCI journals, including European Urology (IF
7.643), the most distinguished and influential journal in urology.
Theses are cited 239 times in all. And the number of scholars
that attended our surgery demonstration at both domestic
and international academic conferences is 9760 person-time.
We host 2006 Asian Urological Association Annual Meeting
Minimally Invasive Surgery Session and attend American
Urological Association (AUA) Annual Meeting to lecture on
our achievement. At the 3rd Greatwall International Andrology
Forum (GIAF2008), the 26th World Congress on Endourology
(WCE) and the 30th Congress of the Société internationale
d'Urologie (SIU), we demonstrated the 2um thulium laser
resection of prostate-tangerine technique (TmLRP-TT).
And we were invited to Germany for academic exchange and
lecture afterwards. Experts of the field speak highly of our work
unanimously both at home and abroad. Now the 2um thulium
laser resection of prostate-tangerine technique (TmLRP-TT) has
been written in textbooks such as Minimally Invasive Urologic
Surgery (published by Shandong Science and Technology
Publishing House), Urological Surgery (published by People's
Mecical Publishing House) and CSU Minimally Invasive Surgery
