“…Goldfarb et al presented a case of accelerated incrustation due to the hypercalciuric situation in pregnancy and emphasized the need for hydration, calcium restriction, and close monitoring to prevent infection and stone formation in pregnancy (18). Peer et al have pointed out the risk of technical difficulties of stent application, anesthesia requirement, and inducing birth, and reported that pain and pyonephrosis were successfully treated with percutaneous nephrostomy in their patients and pregnancy continued uneventfully until birth with preservation of renal function (19). The application of PCN by local anesthesia may provide a significant advantage, especially in the pregnant patient subgroup.…”

“…These studies have demonstrated that DJS is an effective and safe method for the treatment of pregnancy hydronephrosis. Percutaneous nephrostomy has been performed in a small number of cases in a few studies and successful results have been reported (19,(24)(25)(26). Most recently, Khoo et al assessed the shortterm complications and success rate of percutaneous nephrostomy during pregnancy (27).…”

Background/aim: We aimed to compare the success rate of percutaneous nephrostomy (PCN) and double J stenting (DJS) in the treatment of symptomatic pregnancy hydronephrosis.Materials and methods: Diagnosis and grading of hydronephrosis were performed by urinary ultrasound (USG) and Doppler mode was used for evaluation of renal arterial resistivity index (RI). Patients were divided into two groups according to the method used for the treatment of hydronephrosis: group A (PCN, n = 38) and group B (DJS, n = 46). A P value < 0.05 was considered significant. Results:The number of patients requiring second intervention was higher in group B (P = 0.0018) and time to secondary intervention was significantly earlier in group B also (P = 0.0025). The number of tertiary intervention was again higher in group B (5/16 vs. 1/6) and the need for tertiary intervention was higher in patients who underwent DJS implantation as a secondary intervention than those who underwent PCN (5/11 vs. 1/11, P = 0.0012). The time to tertiary intervention was longer in patients with PCN than in those with DJS (P = 0.0048). Conclusion:PCN may be preferred to DJS in symptomatic pregnancy hydronephrosis because it requires fewer re-interventions after longer times.

Background: Obstructed kidney is also termed hydronephrosis. An obstructed kidney produces buildup of urine within the kidney which increases pressure within the kidney. This condition can be a result of several different causes of which pregnancy is one of them. Obstructed kidneys in pregnancy call for relieving by nephrostomy which is a thin, plastic tube (catheter) that is inserted through the skin on the back and into the kidney. It can relieve a build-up of urine in the kidney and prevents the kidney from being damaged. It drains urine directly from one or both kidneys into a collecting bag outside the body. The bag has a tap so it can be emptied. Aims: To find out the rate of nephrostomy tube insertion in pregnant women in North Manchester General Hospital between January 2009 -December 2013. To identify problems that emanated from insertion of the nephrostomies. Results: Fifteen patients out of 24,863 deliveries (0.06%) in our catchment area underwent 17 nephrostomy procedures. All the nephrostomy insertions were successfully and safely undertaken. There was no immediate complication. The complications that were noted include: subsequent blockage of nephrostomy tubes which required readmission to flush the tubes to render them patent, two nephrostomy tubes subsequently fell out which were replaced, there was 1 minor infection which was treated by oral antibiotics. Surgical causes of obstruction found at post-partum nephrostogram include calculi and ureteric strictures which were managed post-partum. All the pregnancies continued to full-term with delivery of normal full-term babies. Conclusions: Percutaneous nephrostomy insertion in the pregnant woman under ultra-sound scan guidance is a safe and effective procedure associated with minimal complications and this allows pregnancy to continue to full term. The fact that the blocked nephostomies could all be flushed easily to unblock the tubes would indicate that if all district nurses are taught how to carefully flush nephrostomies readmission with blocked nephrostomies would be minimised. Strict adherence to nephrostomy protocol would partly help reduce complications associated with nephrostomy insertion in pregnancy.

Advances in nanotechnology have contributed to the development of novel nanoparticles that enable the tumor‐specific delivery of imaging probes and therapeutic agents in cancer imaging and therapy. Nanobiotechnology combines nanotechnology with molecular imaging, which has led to the generation of new multifunctional nanoparticles for cancer imaging and therapy. Multifunctional nanoparticles hold great promise for the future of cancer treatment because they can detect the early onset of cancer in each individual patient and deliver suitable therapeutic agents to enhance therapeutic efficacy. The combination of tumor‐targeted imaging and therapy in an all‐in‐one system provides a useful multimodal approach in the battle against cancer. Novel multifunctional nanoparticles thus offer a new avenue in the application of personalized medicine in the near future. Herein, new trends and the significance of novel multifunctional nanoparticles in cancer imaging and therapy are reviewed.
