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.
