ml/sec at 3 months post-operatively. Only 2 patients’<br />
required bladder irrigation for hematuria and 5% of<br />
patients’ required recatheterization. Similar results were<br />
confirmed by other larger studies that demonstrated that<br />
HoLRP has equivalent or even better results than TURP<br />
(50). In 1999 Gilling et al (51) (level1) published the<br />
results of a prospective randomized trial with 1-year follow-up<br />
of patients assigned to HoLRP (n=61) and TURP<br />
(n=59). The improvement in flow rate and symptoms score<br />
was similar but the operating time was longer in the HoLRP<br />
group, however the nursing contact, catheter time (20 vs<br />
37.2 hours) and hospital stay (26.2 vs 47.5 hours) were<br />
significantly shorter than the TURP group. At 12 months,<br />
8.3% of the HoLRP group and 10.6% in the TURP group<br />
had deterioration in their level of potency compared to the<br />
preoperative level. Retrograde ejaculation developed in<br />
96% and 86% of the HoLRP and TURP groups, respectively.<br />
Re-operations included 1 bladder neck incision in the<br />
HoLRP group and 2 bladder neck incision sand 2 revisions<br />
in the TURP group. The long-term results showed no significant<br />
difference between the two groups in terms of<br />
symptom score or flow rate at 2 years and 4 years follow up<br />
(52). Fraundorfer et al (53) reported a comparison between<br />
HoLRP and TURP in terms of cost effectiveness. HoLRP<br />
offers a 24.5% cost saving over TURP and 93 procedures<br />
annually would cover the initial and maintenance cost of<br />
the laser machine. The 2 major critiques of the HoLRP procedure<br />
are the longer operative time than TURP (average<br />
16 minute) and the resulting difficulties with pathological<br />
interpretation of the resected small pieces of the adenoma<br />
that may have been affected by thermal damage (54).<br />
HOLMIUM LASER ENUCLEATION OF THE PROSTATE<br />
(HoLEP)<br />
Holmium Laser Enucleation of the prostate (HoLEP) is the<br />
most recent step in the evolution of holmium laser prostatectomy.<br />
Refinement of the holmium laser technique and development<br />
of an efficient tissue morcellator have led to the true<br />
anatomic enucleation of a prostatic adenoma of any size.<br />
Ho: YAG laser fiber acts like the index finger of the surgeon<br />
during an open prostatectomy peeling the median and lateral<br />
lobes off the surgical capsule. In contrast to TURP,<br />
HoLEP is equally suitable for small, medium sized and<br />
large prostate glands with a similar clinical outcome that is<br />
independent of the prostate size (55). Randomized comparative<br />
trials (level 1 evidence) have shown similar results<br />
for HoLEP and traditional surgery used to treat BPH. Tan<br />
et al (56) found that HoLEP is superior to TURP for relieving<br />
bladder outlet obstruction. HoLEP is also superior to<br />
TURP with less bleeding, amount of tissue removed,<br />
decreased catheter time and hospital stay (57,58). HoLEP<br />
group in contrast to the TURP group where the transfusion<br />
rate was 3.3%. In another study Montorsi et al (59) found<br />
that HoLEP and TURP were equally effective with similar<br />
rate of complications at 1 year follow-up. The erectile function<br />
did not show a decrease from baseline in either group.<br />
There was no TUR syndrome in the HoLEP group, versus<br />
in 2.2% of patients in the TURP group. Transient urge<br />
incontinence was reported in 44% and 38% of the HoLEP<br />
and TURP groups, respectively. This complication is usual-<br />

ly short term and self-limiting. Urethral stricture occurred<br />
in 1.7% in HoLEP group and 7.4% in the TURP group.<br />
Kuntz et al (60) reported that the AUA symptom scores<br />
improved 13-fold in the HoLEP and more than 5 fold in<br />
the TURP group, however, the maximum flow rate<br />
improved about 5-fold in each group. Of sexually active<br />
patients, 74% in the HoLEP group and 70.3% in the TURP<br />
group had retrograde ejaculation. The operative time was<br />
longer than TURP, which seems to be due to the significant<br />
learning curve of HoLEP, which is the main problem of the<br />
HoLEP Procedure Unlike HoLRP, there are no thermal tissue<br />
artefacts in the enucleated specimen in the HoLEP procedure<br />
which improves the histological assessment compared<br />
to TURP (61) HoLEP has the advantage of safely<br />
treating patients and anticoagulated patients, with low<br />
perioperative morbidity regardless of the prostate size (62).<br />
This justifies the suggestion that HoLEP is the modern<br />
gold standard alternative to TURP and open prostatectomy.<br />
It appears to be at least as effective as the traditional surgery<br />
of BPH in terms of its short and long- term efficacy<br />
and low perioperative complications (63).<br />
BIPOLAR TRANS-URETHRAL RESECTION IN SALINE<br />
(TURIS)<br />
The use of bipolar systems permits the coagulation at a<br />
much lower peak voltage of 65-120 V compared with<br />
monopolar systems of 500-800 V. it has been suggested<br />
that this lower peak volume of energy will cause fewer filling<br />
symptoms after resection than standard monopolar<br />
systems (64). The bipolar resection system makes it possible<br />
to use physiologic 0,9% saline as the irrigation fluid,<br />
which reduces the risk of TUR syndrome (65).<br />
Ho et al (66) presented the outcomes of a single-blind,<br />
prospective randomised trials comparing TURIS and<br />
TURP. TUR syndrome did not occur in the TURIS group.<br />
Recatheterisation (TURIS vs. TURP: 10,4% vs. 7,7%) and<br />
reoperation for bleeding (TURIS vs. TURP: 6,2% vs. 3,8%)<br />
were comparable in the two groups. The mean improvement<br />
rate in terms of flow max, post-voidal residual and<br />
IPSS score assessed at 1, 3, 6 and 12 months postoperatively<br />
was similar in both groups.<br />
CONCLUSION<br />
Various alternative to conventional TURP are currently<br />
available, which seem to have a comparable efficacy and<br />
better safety profile than TURP. However, more long-term<br />
data with follow-up of 5 years are needed to confirm the<br />
efficacy of all these techniques illustrated in many several<br />
study. Faced with the plethora of new, minimally invasive<br />
alternatives to TURP, the question of which modality to<br />
use in any given clinical setting is pertinent. It is apparent<br />
that different groups of clinicians have different skill sets<br />
and access to equipment; this translates in real life practice<br />
to centres that have expertise in certain areas. In reality,<br />
many factors lead to the adoption of a new surgical technology<br />
but only the improved efficacy and safety profiles<br />
are the most important. Until both procedural and contextual<br />
factors are in favour of a shift to a new “gold standard”,<br />
TURP will remain the primary choice for most practicing<br />
urologist.
